98d9d92359 nand/fsl_elbc: detect page size at runtime
This avoids needing a separate U-Boot config when some revisions
of a board have small-page NAND and other revisions have large-page
NAND (except for NAND SPL targets).

CONFIG_FSL_ELBC_FMR is removed -- it was never used nor documented, and
it gets in the way of this change.

956b03e180 mtd: nand: add driver for diskonchip g4 nand flash
This patch adds a driver for the diskonchip G4 nand flash device.  It is based
on the driver from the linux kernel.

This also includes a separate SPL driver.  A separate SPL driver is used because
the device operates in a different mode (reliable mode) when loading a boot
image, and also because the storage format of the boot image is different from
normal data (pages are stored redundantly).  The SPL driver basically mimics how
a typical IPL reads data from the device.  The special operating mode and
storage format are used to compensate for the fact that the IPL does not contain
the BCH ecc decoding algorithm (due to size constraints).  Although the u-boot
SPL *could* use ecc, it operates like an IPL for the sake of simplicity and
uniformity, since the IPL and SPL share the task of loading the u-boot image.
As a side benefit, the SPL driver is very small.

5c651e86ca nand: Add SPL_NAND support to mxc_nand_spl
Add support for generic NAND SPL via the SPL framework into the
mxc_nand_spl driver. This is basically just a simple rename and
publication of the already implemented functions. To avoid the
bare-bones functions getting in the way of the NAND_SPL, build
them only if CONFIG_SPL_FRAMEWORK is not defined.

Also make sure the requested payload is aligned to full pages,
otherwise this simple driver fails to load the last page.

a430e91643 mtd: nand: mxc_nand: Fix is_16bit_nand()
Currently is_16bit_nand() is a per SoC function and it decides the bus nand
width by reading some boot related registers.

This method works when NAND is the boot medium, but does not work if another
boot medium is used. For example: booting from a SD card and then using NAND
to store the environment variables, would lead to the following error:

NAND bus width 16 instead 8 bit
No NAND device found!!!
0 MiB

Use CONFIG_SYS_NAND_BUSWIDTH_16BIT symbol to decide the bus width.

If it is defined in the board file, then consider 16-bit NAND bus-width,
otherwise assume 8-bit NAND is used.

This also aligns with Documentation/devicetree/bindings/mtd/nand.txt, which
states:

nand-bus-width : 8 or 16 bus width if not present 8

c39d6a0ea5 nand: Extend nand_(read|write)_skip_bad with *actual and limit parameters
We make these two functions take a size_t pointer to how much space
was used on NAND to read or write the buffer (when reads/writes happen)
so that bad blocks can be accounted for.  We also make them take an
loff_t limit on how much data can be read or written.  This means that
we can now catch the case of when writing to a partition would exceed
the partition size due to bad blocks.  To do this we also need to make
check_skip_len count not just complete blocks used but partial ones as
well.  All callers of nand_(read|write)_skip_bad are adjusted to call
these with the most sensible limits available.

The changes were started by Pantelis and finished by Tom.

239cb9d904 mtd: cfi_flash: Fix CFI flash driver for 8-bit bus support
This commit is based on that patch from aaron.williams@caviumnetworks.com
with same commit title. pulled the same code changes into current u-boot tree.

http://patchwork.ozlabs.org/patch/140863/
http://lists.denx.de/pipermail/u-boot/2011-April/089606.html

This patch corrects the addresses used when working with Spansion/AMD FLASH chips.
Addressing for 8 and 16 bits is almost identical except in the 16-bit case the
LSB of the address is always 0.  The confusion arose because the addresses
in the datasheet for 16-bit mode are word addresses but this code assumed it was
byte addresses.

I have only been able to test this on our Octeon boards which use either an 8-bit
or 16-bit bus.  I have not tested the case where there's an 8-bit part on a 16-bit
bus.

This patch also adds some delays as suggested by Spansion.

If a part can be both 8 and 16-bits, it forces it to work in 8-bit mode if an
8-bit bus is detected.

Apart from the pulled changes, fixed few minor code cleanups and tested
on 256M29EW, 512M29EW flashes.

Before this fix:

ac6b911514 cfi_flash: Enable PPB protection for all AMD cmdset flash chips
Not only Spansion supports the Persistent Protection Bits (PPB) locking.
Other devices like the Micron JS28F512M29EWx also support this type
of locking/unlocking. Detection of support is done in the same way as
done for the Spansion chips - via the 0x49 CFI word.

This patch enables this PPB protection mechanism for all AMD type
(AMD commandset) chips.

03deff433e cfi_flash: Read PPB sector protection from device for AMD/Spansion chips
Patch 66863b05 [cfi_flash: add support for Spansion flash PPB sector
protection] introduced the PPB (Persistent Protection Bit) locking for
Spansion chips. But right now the sector protection status (locked vs
unlocked) is set to unlocked for all sectors upon bootup. The real
sector protection status is ignored.

This patch now reads the current sector protection status and uses
it for these AMD/Spansion flash chips.

07b2c5c0e5 mtd/cfi: add support for SST 4KB sector granularity
Add support for SST 4KB sector granularity.

Many recent SST flashes, i.e. SST39VF3201B and similar of this family
are declared CFI-conformant from SST. They support CFI query, but implement
2 different sector sizes in the same memory: a 64KB sector (they call it
"block", std AMD erase cmd=0x30), and a 4KB sector (they call it "sector",
erase cmd=0x50). Also, CFI query on these chips, reading from address 0x2dh
of cfi query struct, detects a number of secotrs for the 4KB granularity
(flinfo shows it).

For all other aspects, they are CFI compliant, so, as Linux do, i think
it's a good idea to handle these chips in the CFI driver, with a fixup
to allow 4KB granularity, as should be expected, instead of 64KB.

0b38fffbe4 mtd: nand: mxs: reset BCH earlier, too, to avoid NAND startup problems
It could happen (1 out of 100 times) that NAND did not start up correctly after
warm rebooting, so we end up with various failures or DMA timed out due to a
stalled BCH. When resetting BCH together with GPMI, the issue could not be
observed anymore (after 10000+ reboots). We probably need the consistent state
already before sending commands to NAND. This behaviour was observed in barebox
and kernel, so I assume it affects U-Boot as well. I chose to keep the extra
reset for BCH when changing the flash layout to be on the safe side.

IFC-1.1.0 uses 28nm techenology for SRAM. This tech has known limitaion for
SRAM i.e. "byte select" is not supported. Hence Read Modify Write is
implemented in IFC for any "system side write" into sram buffer. Reading an
uninitialized memory results in ECC Error from sram wrapper.

Hence we must initialize/prefill SRAM buffer by any data before writing
anything in SRAM from system side. To initialize SRAM user can use "READID"
NAND command with read bytes equal to SRAM size. It will be a one time
activity post boot

eef1cf2d5c include/linux/byteorder: import latest endian definitions from linux
u-boot's byteorder headers did not contain endianness attributions
for use with sparse, causing a lot of false positives.  Import the
kernel's latest definitions, and enable them by including compiler.h
and types.h.  They come with 'const' added for some swab functions, so
fix those up, too:

include/linux/byteorder/big_endian.h:46:2: warning: passing argument 1 of '__swab64p' discards 'const' qualifier from pointer target type [enabled by default]

Also, note: u-boot's historic __BYTE_ORDER definition has been
preserved (for the time being at least).

We also remove ad-hoc barrier() definitions, since we're including
compiler.h in files that hadn't in the past:

macb.c:54:0: warning: "barrier" redefined [enabled by default]

In addition, including compiler.h in byteorder changes the 'noinline'
definition to expand to __attribute__((noinline)).  This fixes
arch/powerpc/lib/bootm.c:

bootm.c:329:16: error: attribute '__attribute__': unknown attribute
bootm.c:329:16: error: expected ')' before '__attribute__'
bootm.c:329:25: error: expected identifier or '(' before ')' token

powerpc sparse builds yield:

include/common.h:356:22: error: marked inline, but without a definition

the unknown-reason inlining without a definition is considered obsolete
given it was part of the 2002 initial commit, and no arm version was
'fixed.'

This is based on Linux kernel -next:

Author: Brian Norris <computersforpeace@gmail.com>

    mtd: nand: allow NAND_NO_SUBPAGE_WRITE to be set from driver

    The NAND_CHIPOPTIONS_MSK has limited utility and is causing real bugs. It
    silently masks off at least one flag that might be set by the driver
    (NAND_NO_SUBPAGE_WRITE). This breaks the GPMI NAND driver and possibly
    others.

    Really, as long as driver writers exercise a small amount of care with
    NAND_* options, this mask is not necessary at all; it was only here to
    prevent certain options from accidentally being set by the driver. But the
    original thought turns out to be a bad idea occasionally. Thus, kill it.

    Note, this patch fixes some major gpmi-nand breakage.

bdfd59aa0f at91: atmel_nand: Update driver to support Programmable Multibit ECC controller
The Programmable Multibit ECC (PMECC) controller is a programmable binary
BCH(Bose, Chaudhuri and Hocquenghem) encoder and decoder. This controller
can be used to support both SLC and MLC NAND Flash devices. It supports to
generate ECC to correct 2, 4, 8, 12 or 24 bits of error per sector of data.

To use PMECC in this driver, the user needs to set the PMECC correction
capability, the sector size and ROM lookup table offsets in board config file.

This driver is ported from Linux kernel atmel_nand PMECC patch. The main difference
is in this version it uses registers structure access hardware instead of using macros.
It is tested in 9x5 serial boards.

"For the beagleboard, ecc.size is not explicitly set when doing 'nandecc

set to 256 bytes.

When doing 'nandecc hw', ecc.size is set to 512 bytes. Hence, when
changing back to 'nandecc sw' ecc.size remains at 512 bytes and suddenly
the format has changed."

No patch has been submitted and the issue was still present. This patch
adds the mentioned solution. Tested on a tam3517 board.

be set within the stipulated time. However, there may occur a scenario in which
the TFF flag is not set. Return error in that case.

f3fcf92d59 st_smi: Add support for SPEAr SMI driver
SMI is the serial memory interface controller provided by ST.

Earlier, a driver exists in the u-boot source code for the SMI IP. However, it
was specific to spear platforms. This commit converts the same driver to a more
generic driver. As a result, the driver files are renamed to st_smi.c and
st_smi.h and moved into drivers/mtd folder for reusability by other platforms
using smi controller peripheral.

96666a39ae DMA: Split the APBH DMA init into block and channel init
This fixes the issue where mxs_dma_init() was called either twice or never,
without introducing any new init hooks.

The idea is to allow each and every device using the APBH DMA block to
configure and request only the channels it uses, instead of making it call init
for all the channels as is now.

The common DMA block init part, which only configures the block, is then called
from CPUs arch_cpu_init() call.

start by looking at what NAND driver the board selects, and whether

a9f5faba6e * Fix: watchdog timed out, if flash blank (0xFF) blocks
The current implementation of cfi_flash uses udelay to reset watchdog.
If several blocks are blank (0xff filled) the watchdog timed out.
The reason is, udelay is never called, if flash device is ready to fast.

e.g.
     mw.w $(copy_addr) FFFF 10000;cp.b $(copy_addr) 10880000 20000

     -> watchdog timed out

     mw.w $(copy_addr) 0000 10000;cp.b $(copy_addr) 10880000 20000

     -> watchdog not timed out

This patch adds an extra watchdog reset in front of flash ready check.

56c91bc3b6 Fix regression in SMDK6400
s3c64xx.c implemented its own nand_read_byte, nand_write_buf and
nand_read_buf functions. This provoked a regression when these functions
were made public by patch 55f429bb39614a16b1bacc9a8bea9ac01a60bfc8.

This deletes these duplicated functions from s3c64xx.c and adds the generic
implementations in nand_base.c to the spl Makefile. It also adds
-ffcuntion-sections and -gc-sections to the compilation flags of the SPL to
avoid errors originating from unused functions in nand_base.c.

d63894654d UBI: init eba tables before wl when attaching a device
This fixes that u-boot gets stuck when a bitflip was detected
during "ubi part <ubi_device>". If a bitflip was detected UBI tries
to copy the PEB to a different place. This needs that the eba table
are initialized, but this was done after the wear levelling worker
detects the bitflip. So changes the initialisation of these two
tasks in u-boot.

This is a u-boot specific patch and not needed in the linux layer,
because due to commit 1b1f9a9d00
UBI: Ensure that "background thread" operations are really executed
we schedule these tasks in place and not as in linux after the inital
task which schedule this new task is finished.

6016194371 NAND: davinci: choose correct 1-bit h/w ECC reg
In nand_davinci_readecc(), select the correct NANDF<n>ECC register based
on CONFIG_SYS_NAND_CS rather than hardcoding the choice of NANDF1ECC.
This allows 1-bit hardware ECC to work with chip select other than CS2.

Note this now matches the usage in nand_davinci_enable_hwecc(), which
already had the correct handling, and allows refactoring to a single
function encapsulating the register read.

Without this fix, writing NAND pages to a chip not wired to CS2 would
result in in the ECC calculation always returning FFFFFF for each
512-byte segment, and reading back a correctly written page (one with
ECC intact) would always fail. With this fix, the ECC is written and
verified correctly.

b4b1e769b8 mxc_nand: fix a problem writing more than 32MB
When writing 0x4000 to the unlockend_blkaddr register, large writes to
a 2k page NAND sometimes fail. The current kernel driver writes 0xFFFF
to this register for V2 of the nand controller.

However on an i.MX31 this also fixes writes larger than 32MB.
The datasheet is very unspecific, but (0x4000=16384)*2000
roughly fits the limits we're encountering with NAND writes.
This problem might be NAND chip specific.

52f90dad60 nand: Freescale Integrated Flash Controller NAND support
Add NAND support (including spl) on IFC, such as is found on the p1010.

Note that using hardware ECC on IFC with small-page NAND (which is what
comes on the p1010rdb reference board) means there will be insufficient
OOB space for JFFS2, since IFC does not support 1-bit ECC.  UBI should
work, as it does not use OOB for anything but ECC.

When hardware ECC is not enabled in CSOR, software ECC is now used.

eced4626e4 NAND: Add 16bit NAND support for the NDFC
This patch adds support for 16 bit NAND devices attached to the
NDFC on ppc4xx processors. Two config entries were added:

  CONFIG_SYS_NDFC_16        - Setting this tells the NDFC that a
			      16 bit device is attached.
  CONFIG_SYS_NDFC_EBC0_CFG  - This is for the External Bus
			      Controller configuration register.

Also, a new ndfc_read_byte() function was added which does not
first convert the data to little endian.

The NAND SPL was also modified to do 16bit bad block testing
when a 16 bit chip is being used.

Convert the only flag currently passed to the nand_write_

end of the parameter list or the ambiguous calls like

nand_write_skip_bad(info, offset, len, buf, 0, 1, 1);
nand_write_skip_bad(info, offset, len, buf, 0, 1, 0);

Instead there will be:

			WITH_OTHER);

aad99bbc39 NAND: rearrange ONFI revision checking, add ONFI 2.3
This patch sync with Brian's patch on Linux in nand_flash_detect_onfi()

	Author: Brian Norris <computersforpeace@gmail.com>
	Date:   Sun Dec 12 00:23:33 2010 -0800

	    mtd: nand: rearrange ONFI revision checking, add ONFI 2.3

	    In checking for the ONFI revision, the first conditional (for checking
	    "unsupported" ONFI) seems unnecessary.  All ONFI revisions should be
	    backwards-compatible; even if this is not the case on some newer ONFI
	    revision, it should simply fail the second version-checking if-else block
	    (i.e., the bit-fields for 1.0, 2.0, etc. would not be set to 1). Thus, we
	    move our "unsupported" condition after having checked each bit field.

	    Also, it's simple enough to add a condition for ONFI revision 2.3. Note
	    that this does *NOT* mean we handle all new features of ONFI versions
	    above 1.0.

device supporting it. If this is the case, struct nand_chip onfi_version
member contains the supported ONFI version, 0 otherwise.

This allows NAND drivers past nand_scan_ident to set the best timings for the
NAND chip.

af56730153 cfi_flash: fix bug with flash banks with different sector numbers
The function find_sector() does not take into account if the flash bank
has changed since the last call. This could lead to illegal accesses inside
and beyond the flash_info_t info strcture. For example if the current
flash bank has less sectors than the last used flash bank.

This patch adds two cheks. One that insures, that the current sector does
not exceed the allowed maximum (which is always a good idea). And one that
checks if the current access is to the same flash bank as the last access.
If not, the search loop will start with sector 0.

34bbb8fb46 cfi_flash: fix bug introduced while recent change to flash_get_size()
commit ec50a8e389
"cfi_flash: handle 'chip size exceeds address window' situation"
added 3rd argument to flash_get_size() but didn't fix all the
function calls from the board specific code. Many boards have
their own flash_get_size() definitions in the board code and
use them there, but some boards (e.g. tqm834x, tqm85xx, pdm360ng)
use flash_get_size() from the cfi_flash.c driver.

The bug shows up if the value of the "max_size" argument (which
is not defined when calling the function with two arguments)
happens to be less than "info->size". In this case on the
affected boards we end up with a bank of reduced size and
in the worst case might even be not able to update U-Boot or
to boot the kernel from flash:

=> fli

Bank # 1: CFI conformant FLASH (32 x 16)  Size: 0 kB in 1 Sectors
  AMD Standard command set, Manufacturer ID: 0x01, Device ID: 0x227E
  Erase timeout: 4096 ms, write timeout: 1 ms
  Buffer write timeout: 3 ms, buffer size: 64 bytes

  Sector Start Addresses:
  F0000000   RO

Bank # 2: CFI conformant FLASH (32 x 16)  Size: 128 MB in 512 Sectors
  AMD Standard command set, Manufacturer ID: 0x01, Device ID: 0x227E
  Erase timeout: 4096 ms, write timeout: 1 ms
  Buffer write timeout: 3 ms, buffer size: 64 bytes

  Sector Start Addresses:
  F8000000        F8040000        F8080000        F80C0000        F8100000
  F8140000        F8180000        F81C0000        F8200000        F8240000
  ...

E.g., updating U-Boot is not possible now:

=> protect off ${u-boot_addr} +${u-boot_size}
Error: end address (0xf007ffff) not in flash!
Bad address format
=> era ${u-boot_addr} +${u-boot_size}
Error: end address (0xf007ffff) not in flash!
Bad address format

This patch removes the 3rd argument of flash_get_size() again
and sets "max_size" in the function itself instead of passing
it as a function argument.

6d8962e814 Switch from archive libraries to partial linking
Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils.  As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".

This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.

The name of each former library archive is preserved except for
extensions which change from ".a" to ".o".  This commit updates
references accordingly where needed, in particular in some linker
scripts.

This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols.  Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

ec50a8e389 cfi_flash: handle 'chip size exceeds address window' situation
On some boards we have flash mapped high in the address space with
considerably small window (say 0xFE000000 and 32MB). When we install
bigger chip (say 64MB) on such a board strange things happen
(flash_write() doesn't work at all, for ex). That's because cfi_flash
driver doesn't care about window size at all.
Of course, cleanest solution would probably be to just extend address
window to be able to map the whole flash but for legacy/compatibility
reasons some people prefer just truncate the flash size and never use
the upper part.
This patch adds an option for cfi_flash driver to handle this situation
properly. To achieve this we add the new function cfi_flash_bank_size()
which can be provided by the board code and weak-aliased to default
implementation that returns value from the CONFIG_SYS_FLASH_BANKS_SIZES
array if it's defined or 0 otherwise (the last case is added for
compatibility).
If non-zero flash bank size is provided and detected chip size is bigger
than provided address window size the warning will be displayed and
flash chip will be truncated.

3048632251 nand erase: .spread, .part, .chip subcommands
A while back, in http://lists.denx.de/pipermail/u-boot/2009-June/054428.html,
Michele De Candia posted a patch to not count bad blocks toward the
requested size to be erased.  This is desireable when you're passing in
something like $filesize, but not when you're trying to erase a partition.

Thus, a .spread subcommand (named for consistency with
http://lists.denx.de/pipermail/u-boot/2010-August/075163.html) is introduced
to make explicit the user's desire to erase for a given amount of data,
rather than to erase a specific region of the chip.

While passing $filesize to "nand erase" is useful, accidentally passing
something like $fliesize currently produces quite unpleasant results, as the
variable evaluates to nothing and U-Boot assumes that you want to erase
the entire rest of the chip/partition.  To improve the safety of the
erase command, require the user to make explicit their intentions by
using a .part or .chip subcommand.  This is an incompatible user interface
change, but keeping compatibility would eliminate the safety gain, and IMHO
it's worth it.

While touching nand_erase_opts(), make it accept 64-bit offsets and sizes,
fix the percentage display when erase length is rounded up, eliminate
an inconsistent warning about rounding up the erase length which only
happened when the length was less than one block (rounding up for $filesize
is normal operation), and add a diagnostic if there's an attempt to erase
beginning at a non-block boundary.

f9a5254111 nand util: read/write: accept unaligned length
The underlying code in nand_base.c already supports non-page-aligned reads
and writes, but the block-skipping wrapper code did not.

With block skipping, an unaligned start address is not useful since you
really want to be starting at the beginning of a partition -- or at least
that's where you want to start checking for blocks to skip, but we don't
(yet) support that.  So we still require the start address to be aligned.

An unaligned length, though, is useful for passing $filesize to the
read/write command, and handling it does not complicate block skipping.

ca5def3f30 cfi_flash: Simplify dynamic flash bank number detection
This patch simplifies the use of CONFIG_SYS_MAX_FLASH_BANKS_DETECT. By
moving these optional variables and defines into the common code, board
specific code is minimized. Currently only the following board use
this feature:

APC405, IDS8247, TQM834x

And IDS8247 doesn't seem to really need this feature, since its not
updating the bank number variable at all. So this patch removes the
definition of CONFIG_SYS_MAX_FLASH_BANKS_DETECT from this board port.

This new framework will be used by the upcoming lwmon5 update as well.

b00e19cc6b cfi_flash: Add weak default for cfi_flash_bank_addr()
cfi_flash_bank_addr(int bank_nr) returns the base addresses of the
requested bank. Introducing this weak default enables boards to override
this functions with a board specific version when required.

This feature will be used in the lwmon5 board update, supporting runtime
detection of 2 board revisions with different flash layouts.

54652991ca Work around bug in Numonyx P33/P30 256-Mbit 65nm flash chips.
I have "ported" U-boot to a in house made board with Numonyx Axcell P33/P30
256-Mbit 65nm flash chips.

After some time :( searching for bugs in our board or soft, we have
discovered that those chips have a small but annoying bug, documented in
"Numonyx Axcell P33/P30 256-Mbit Specification Update"

It states :
When customer uses [...] block unlock, the block lock status might be
altered inadvertently. Lock status might be set to either 01h or 03h
unexpectedly (00h as expected data), which leads to program/erase failure
on certain blocks.

A working workaround is given, which I have applied and tested with success :

Workaround:  If the interval between 60h and its subsequent command
	     can be guaranteed within 20us, Option I is recommended,
	     otherwise Option II (involves hardware) should be selected.
Option I: The table below lists the detail command sequences:
Command
	      Data bus           Address bus       Remarks
Sequence
  1              90h            Block Address
						   Read Lock Status
  2             Read         Block Address + 02h
 (2)(3)                                      (1)
3                60h           Block Address
 (2)(3)                                      (1)   Lock/Unlock/RCR Configuration
4           D0h/01h/03h        Block Address
Notes:
(1) Block Address refers to RCR configuration data only when the 60h
    command sequence is used to set RCR register combined with 03h
    subsequent command.
(2) For the third and fourth command sequences, the Block Address must
    be the same.
(3) The interval between 60h command and its subsequent D0h/01h/2Fh/03h
    commands should be less than 20us.

And here is a log comparison of a simple (destructive) flash test without
and with the workaround.

cdb749778a Rename getenv_r() into getenv_f()
While running from flash, i. e. before relocation, we have only a
limited C runtime environment without writable data segment. In this
phase, some configurations (for example with environment in EEPROM)
must not use the normal getenv(), but a special function.  This
function had been called getenv_r(), with the idea that the "_r"
suffix would mean the same as in the _r_eentrant versions of some of
the C library functions (for example getdate vs. getdate_r, getgrent
vs. getgrent_r, etc.).

Unfortunately this was a misleading name, as in U-Boot the "_r"
generally means "running from RAM", i. e. _after_ relocation.

To avoid confusion, rename into getenv_f() [as "running from flash"]

f51cdaf191 83xx/85xx/86xx: LBC register cleanup
Currently, 83xx, 86xx, and 85xx have a lot of duplicated code
dedicated to defining and manipulating the LBC registers.  Merge
this into a single spot.

To do this, we have to decide on a common name for the data structure
that holds the lbc registers - it will now be known as fsl_lbc_t, and we
adopt a common name for the immap layouts that include the lbc - this was
previously known as either im_lbc or lbus; use the former.

In addition, create accessors for the BR/OR regs that use in/out_be32
and use those instead of the mismash of access methods currently in play.

I have done a successful ppc build all and tested a board or two from
each processor family.

returns before it has had a chance to drain.  On faster systems, this
isn't a problem as the operation finishes before the ECC registers are

to read it.

So wait for the buffer to drain once we're done writing to it.

22d6c8faac cfi_flash: reset timer in flash status check
This patch adds reset_timer() before the flash status check
waiting loop.

Since the timer is basically running asynchronous to the cfi
code, it is possible to call get_timer(0), then only a few
_SYSCLK_ cycles later an interrupt is generated. This causes
timeout even though much less time has elapsed. So the timer
period registers should be reset before get_timer(0) is
called.

There is similar usage in nand_base.c.
