If we change to software ecc and then back to hardware ecc, the nand ecc ops
pointers are populated with incorrect function pointers. This is related to the
way nand_scan_tail() handles assigning functions to ecc ops:
If we are switching to software ecc/no ecc, it assigns default functions to the
ecc ops pointers unconditionally, but if we are switching to hardware ecc,
the default hardware ecc functions are assigned to ops pointers only if these
pointers are NULL (so that drivers could set their own functions). In the case
of omap_gpmc.c driver, when we switch to sw ecc, sw ecc functions are
assigned to ecc ops by nand_scan_tail(), and when we later switch to hw ecc,
the ecc ops pointers are not NULL, so nand_scan_tail() does not overwrite
them with hw ecc functions.
The result: sw ecc functions used to write hw ecc data.
Clear the ecc ops pointers in omap_gpmc.c when switching ecc types, so that
ops which were not assigned by the driver will get the correct default values
from nand_scan_tail().

When switching ecc mode, omap_select_ecc_scheme() assigns the appropriate values
into the current nand chip's ecc.layout struct. This is done under the
assumption that the struct exists only to store values, so it is OK to overwrite
it, but there is at least one situation where this assumption is incorrect:
When switching to 1 bit hamming code sw ecc, the job of assigning layout data
is outsourced to nand_scan_tail(), which simply assigns into ecc.layout a
pointer to an existing struct prefilled with the appropriate values. This struct
doubles as both data and layout definition, and therefore shouldn't be
overwritten, but on the next switch to hardware ecc, this is exactly what's
going to happen. The next time the user switches to software ecc, they're
going to get a messed up ecc layout.
Prevent this and possible similar bugs by explicitly using the
private-to-omap_gpmc.c omap_ecclayout struct when switching ecc mode.

Commit "mtd: nand: omap: enable BCH ECC scheme using ELM for generic
platform" (d016dc42ce) changed the way
software ECC is configured, both during boot, and during ecc switch, in a way
that is not backwards compatible with older systems:
Older version of omap_gpmc.c always assigned ecc.size = 0 when configuring
for software ecc, relying on nand_scan_tail() to select a default for ecc.size
(256), while the new version of omap_gpmc.c assigns ecc.size = pagesize,
which is likely to not be 256.
Since 1 bit hamming sw ecc is only meant to be used by legacy devices, revert
to the original behavior.

As per OMAP3530 TRM referenced below [1]
For large-page NAND, ROM code expects following ecc-layout for HAM1 ecc-scheme
- OOB[1] (offset of 1 *byte* from start of OOB) for x8 NAND device
- OOB[2] (offset of 1 *word* from start of OOB) for x16 NAND device
Thus ecc-layout expected by ROM code for HAM1 ecc-scheme is:
*for x8 NAND Device*
+--------+---------+---------+---------+---------+---------+---------+
| xxxx | ECC[A0] | ECC[A1] | ECC[A2] | ECC[B0] | ECC[B1] | ECC[B2] | ...
+--------+---------+---------+---------+---------+---------+---------+
*for x16 NAND Device*
+--------+--------+---------+---------+---------+---------+---------+---------+
| xxxxx | xxxxx | ECC[A0] | ECC[A1] | ECC[A2] | ECC[B0] | ECC[B1] | ECC[B2] |
+--------+--------+---------+---------+---------+---------+---------+---------+
This patch fixes ecc-layout *only* for HAM1, as required by ROM-code
For other ecc-schemes like (BCH8) ecc-layout is same for x8 or x16 devices.

Writing zero into I2Ci.I2C_CNT register causes random I2C failures in OMAP3

OMAP4430 TRM:
Advisory:
I2C Module Does Not Allow 0-Byte Data Requests
Details:
When configured as the master, the I2C module does not allow 0-byte data
transfers. Note: Programming I2Ci.I2C_CNT[15:0]: DCOUNT = 0 will cause
undefined behavior.
Workaround(s):
No workaround. Do not use 0-byte data requests.
The writes in question are unnecessary from a functional point of view.
Most of them are done after I/O has finished, and the only one that preceds
I/O (in i2c_probe()) is also unnecessary because a stop bit is sent before
actual data transmission takes place.
Therefore, remove all writes that zero the cnt register.

Access to privlist[1] (hardcoded referece to the 2nd tsec's
priv area) is neither correct nor does it make sense in the
current context. Each tsec dev has access to its own priv
instance only, and hence to its own set of group address
registers (GADDR) to filter multicast addresses.
This fix leads to removal of the unused (faulty) privlist[]
and related global static vars. Note that mcast() can be
called only after eth_device allocation and init, and hence
after priv area allocation, so dev->priv is correctly

Patch: 278989
It's important that buffer descriptors are aligned in accordance to GMAC
data bus width (32/64/128-bit). It's safe to align to 128-bit (16-bytes)
for every bus width type.
If buffer descriptor is improperly aligned GMAC discards lower bits of
provided address and as a result reads from improper location that
doesn't match expected fields.
Commit ef76025a99 "net: Multiple
updates/enhancements to designware.c" introduced another structure
member "link_printed" right before buffer descriptors while "padding"
member was left untouched. This together with alignment of structure
itself to 16-byte boundary forces buffer descriptoprs always to be
4-byte aligned that causes driver complete disfunction if GMAC bus width
is 64 or 128-bit.
Proposed change makes sure all buffer descriptors are 16-byte (128-bit)
aligned.

"bus mode" register contains lots of fields and some of them don't
expect to be written with 0 (zero). So since we're only interested in
resetting MAC (which is done with setting the least significant bit of
this register with "0") I believe it's better to modify only 1 bit of
the register.

Patch: 276473
The 'get_phy_driver' code in 'drivers/net/phy/phy.c' uses the following
method to determine which driver is to be loaded for a particular PHY
module:
list_for_each(entry, &phy_drivers) {
drv = list_entry(entry, struct phy_driver, list);
if ((drv->uid & drv->mask) == (phy_id & drv->mask))
return drv;
}
This means that a drv->mask of 0xfffff0 will return incorrect phy driver
for the logic above, even if the drv->uid is anything other than
something ending with a 0x0.
For e.g. if the RTL8211E drv->uid is 0x1cc915 and drv->mask is 0xffffff
and the RTL8211B drv->uid is 0x1cc910 and drv->mask is 0xffffff0, then
the phy driver selected will always be RTL8211B even though the
underlying phy connected on the board is a 8211E module.

This patch adds new CONFIG_NAND_OMAP_ECCSCHEME, replacing other distributed
CONFIG_xx used for selecting NAND ecc-schemes.
This patch aims at solving following issues.
1) Currently ecc-scheme is tied to SoC platform, which prevents user to select
other ecc-schemes also supported in hardware. like;
- most of OMAP3 SoC platforms use only 1-bit Hamming ecc-scheme, inspite
the fact that they can use higher ecc-schemes like 8-bit ecc-schemes with
software based error detection (OMAP_ECC_BCH4_CODE_HW_DETECTION_SW).
- most of AM33xx SoC plaforms use 8-bit BCH ecc-scheme for now, but hardware
supports BCH16 ecc-scheme also.
2) Different platforms use different CONFIG_xx to select ecc-schemes, which
adds confusion for user while migrating platforms.
- *CONFIG_NAND_OMAP_ELM* which enables ELM hardware engine, selects only
8-bit BCH ecc-scheme with h/w based error-correction (OMAP_ECC_BCH8_CODE_HW)
whereas ELM hardware engine supports other ecc-schemes also like; BCH4,
and BCH16 (in future).
- *CONFIG_NAND_OMAP_BCH8* selects 8-bit BCH ecc-scheme with s/w based error
correction (OMAP_ECC_BCH8_CODE_HW_DETECTION_SW).
- *CONFIG_SPL_NAND_SOFTECC* selects 1-bit Hamming ecc-scheme using s/w library
Thus adding new *CONFIG_NAND_OMAP_ECCSCHEME* de-couples ecc-scheme dependency
on SoC platform and NAND driver. And user can select ecc-scheme independently
foreach board.
However, selection some hardware based ecc-schemes (OMAP_ECC_BCHx_CODE_HW) still
depends on presence of ELM hardware engine on SoC. (Refer doc/README.nand)

BCH8_ECC scheme implemented in omap_gpmc.c driver has following favours

|OMAP_ECC_BCH8_CODE_HW_DETECTION_SW |GPMC |S/W BCH library |
+-----------------------------------+-----------------+-----------------+
Current implementation limits the BCH8_CODE_HW only for AM33xx device family.
(using CONFIG_AM33XX). However, other SoC families (like TI81xx) also have
ELM hardware module, and can support ECC error detection using ELM.
This patch
- removes CONFIG_AM33xx
Thus this driver can be reused by all devices having ELM h/w engine.
- adds omap_select_ecc_scheme()
A common function to handle ecc-scheme related configurations. This
can be used both during device-probe and via user-space u-boot commads
to change ecc-scheme. During device probe ecc-scheme is selected based
on CONFIG_NAND_OMAP_ELM or CONFIG_NAND_OMAP_BCH8
- enables CONFIG_BCH
S/W library (lib/bch.c) required by OMAP_ECC_BCHx_CODE_HW_DETECTION_SW
is enabled by CONFIG_BCH.
- enables CONFIG_SYS_NAND_ONFI_DETECTION

nand_ecclayout is present in mtd.h at Linux.
Move this structure to mtd.h to comply with Linux.
Also, increase the ecc placement locations to 640 to suport device having
writesize/oobsize of 8KB/640B. This means that the maximum oobsize has gone
up to 640 bytes and consequently the maximum ecc placement locations have
also gone up to 640.
Changes from Prabhabkar's version (squashed into one patch to preserve
bisectability):
- Added _LARGE to MTD_MAX_*_ENTRIES
This makes the names match current Linux source, and resolves
a conflict between
http://patchwork.ozlabs.org/patch/280488/
and
http://patchwork.ozlabs.org/patch/284513/
The former was posted first and is closer to matching Linux, but
unlike Linux it does not add _LARGE to the names. The second adds
_LARGE to one of the names, and depends on it in a subsequent patch
(http://patchwork.ozlabs.org/patch/284512/).
- Made max oobfree/eccpos configurable, and used this on tricorder,
alpr, ASH405, T4160QDS, and T4240QDS (these boards failed to build
for me without doing so, due to a size increase).
On tricorder SPL, this saves 2576 bytes (and makes the SPL build
again) versus the new default of 640 eccpos and 32 oobfree, and
saves 336 bytes versus the old default of 128 eccpos and 8 oobfree.

If no softreset save registers are found on the hardware
"bootcount" is stored in the environment. To prevent a
saveenv on all reboots, the environment variable
"upgrade_available" is introduced. If "upgrade_available" is
0, "bootcount" is always 0 therefore no need to save the
environment on u-boot boot, if "upgrade_available" is 1 "bootcount"
is incremented in the environment and environment gets written
on u-boot start.
So the Userspace Applikation must set the "upgrade_available"
and "bootcount" variable to 0 (for example with fw_setenv),
if a boot was successfully.

This patch adds support for running on Malta boards using coreFPGA6
core cards, including support for the msc01 system controller used
with them. The system controller is detected at runtime allowing one
U-boot binary to run on a Malta with either.
Due to the PCI I/O base differing between Maltas using gt64120 & msc01
system controllers, the UART setup is modified slightly. A second UART
is added so that there is one pointing at the correct address for each
system controller. The Malta board then defines its own
default_serial_console function to select the correct one at runtime.
The incorrect UART will simply not function.
Tested on:
- A coreFPGA6 Malta running interAptiv and proAptiv bitstreams, both
with and without an L2 cache.
- QEMU.

On relatively slow boards (such as the MIPS Malta with an FPGA core
card) it can be extremely common for transmits to underflow - to the
point where it appears they simply do not work at all. Setting the
NOUFLO bit causes the ethernet controller to not begin transmission on
the wire until a transmit start point is reached. Setting that transmit
start point to the full packet will cause the controller to only
transmit the packet once it has buffered it entirely thus preventing any
transmit underflows from occuring and allowing the controller to
function on slower boards.

Netconsole loses the second character when used as input by
either setenv stdin nc or setenv stdin serial,nc if using CONSOLE_CONSOLE_MUX
Before a nc_send_packet() to echo the input, a check is done to see if
nc_ether is valid. If its not, it waits for an arp request and then sends
the packet (which contains the first character of line to be displayed as
output). As part of reaping the arp request, the second character is consumed.
We protect this by making the call to NetLoop(NETCONS) between
input_recursion.

Nowhere pass a value to len, which always 0, make no transfer which
cause uploading failed.
This patch make nand upload working. However it needs enough malloc
buffer to store read data, that means the buffer at least equal to
the upload partition size, or else it doesn't work.
