A lot changed in the Linux MTD code, since it was last ported from
Linux to U-Boot. This patch takes U-Boot NAND support to the level
of Linux 2.6.22.1 and will enable support for very large NAND devices
(4KB pages) and ease the compatibility between U-Boot and Linux

This patch is tested on two custom boards with PPC and ARM

Except for the issues mentioned above, I have ported all drivers
necessary to run MAKEALL ppc/arm without errors and warnings. Many
drivers were trivial to port, but some were not so trivial. The
following drivers must be examined carefully and maybe rewritten to
some degree:

This is a re-write of the NAND FSL UPM driver using the more universal
hwcontrol callback (instead of the cmdfunc callback). Here is a brief
list of furher modifications:
- For the time being, the UPM setup writing the UPM array has been
removed from the driver and must now be done by the board specific
code.
- The bus width definition in "struct fsl_upm_nand" is now in bits to
comply with the corresponding Linux driver and 8, 16 and 32 bit
accesses are supported.
- chip->dev_read is only set if fun->dev_ready != NULL, which is
required for boards not connecting the R/B pin.
- A few issue have been fixed with MxMR bit manipulation like in the
corresponding Linux driver.
Note: I think the "io_addr" field of "struct fsl_upm" could be removed
as well, because the address is already determined by
"nand->IO_ADDR_[RW]", but I'm not 100% sure.

According to the Application Notes of the DM9000, only the 2 bits 0:1 of
the status byte need to be checked to identify a valid packet in the fifo
But, The several different Application Notes do not all speak the same
language on these bits. They do not disagree, but only 1 Application Note
noted explicitly that only these 2 bits need to be checked.
Even the datasheets do not mention anything about these 2 bits.
Because the old code, and the kernel check the whole byte, I left this piece
untouched.
However, I tested all board/DM9000[A|E|EP] devices with this 2 bit check, so
it should work.
Notice, that the 2nd iteration through this receive loop (when a 2nd packet is
in the fifo) is much shorter now, compared to the older U-boot driver code,
so that we can maybe run into a hardware condition now that was never seen
before, or maybe was seen very unfrequently.

The DM9000A network controller does not work with the U-boot DM9000x driver.
Analysis showed that many incoming packets are lost.
The DM9000A Application Notes V1.20 (section 5.6.1) recommend that the poll to
check for a valid rx packet be done on the interrupt status register, not
directly by performing the dummy read and the rx status check as is currently
the case in the u-boot driver.
When the recommended poll is done as suggested the driver starts working
correctly on 10Mbit/HD, but on 100MBit/FD packets come in faster so that there
can be more than 1 package in the fifo at the same time.
The driver must perform the rx-status check in a loop and read and handle all
packages until there is no more left _after_ the interrupt RX flag is set.

The U-boot DM9000x driver contains a compile time bus-width definition for

This compile check makes the code unclear, inflexible and is unneccessary.
It can be asked to the network controller what its bus-width is by reading bits
6 and 7 of the interrupt status register.
The linux kernel already uses a runtime mechanism to determine this bus-width,
so the implementation below looks somewhat like that implementation.

Changed in v4:
- Update to new API
- Handle zero-length transfers appropriately. The user may send a
zero-length SPI transfer with SPI_XFER_END set in order to
deactivate the chip select after a series of transfers with chip
select active. This is useful e.g. when polling the status
register of DataFlash.
Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
This patch gets rid of the spi_chipsel table and adds a handful of new
functions that makes the SPI layer cleaner and more flexible.
Instead of the spi_chipsel table, each board that wants to use SPI
gets to implement three hooks:
* spi_cs_activate(): Activates the chipselect for a given slave
* spi_cs_deactivate(): Deactivates the chipselect for a given slave
* spi_cs_is_valid(): Determines if the given bus/chipselect
combination can be activated.
Not all drivers may need those extra functions however. If that's the
case, the board code may just leave them out (assuming they know what
the driver needs) or rely on the linker to strip them out (assuming
--gc-sections is being used.)
To set up communication parameters for a given slave, the driver needs
to call spi_setup_slave(). This returns a pointer to an opaque
spi_slave struct which must be passed as a parameter to subsequent SPI
calls. This struct can be freed by calling spi_free_slave(), but most
driver probably don't want to do this.
Before starting one or more SPI transfers, the driver must call
spi_claim_bus() to gain exclusive access to the SPI bus and initialize
the hardware. When all transfers are done, the driver must call
spi_release_bus() to make the bus available to others, and possibly
shut down the SPI controller hardware.
spi_xfer() behaves mostly the same as before, but it now takes a
spi_slave parameter instead of a spi_chipsel function pointer. It also
got a new parameter, flags, which is used to specify chip select
behaviour. This may be extended with other flags in the future.
This patch has been build-tested on all powerpc and arm boards
involved. I have not tested NIOS since I don't have a toolchain for it
installed, so I expect some breakage there even though I've tried
fixing up everything I could find by visual inspection.
I have run-time tested this on AVR32 ATNGW100 using the atmel_spi and
DataFlash drivers posted as a follow-up. I'd like some help testing
other boards that use the existing SPI API.
But most of all, I'd like some comments on the new API. Is this stuff
usable for everyone? If not, why?
Changed in v4:
- Build fixes for various boards, drivers and commands
- Provide common struct spi_slave definition that can be extended by
drivers
- Pass a struct spi_slave * to spi_cs_activate and spi_cs_deactivate
- Make default bus and mode build-time configurable
- Override default SPI bus ID and mode on mx32ads and imx31_litekit.
Changed in v3:
- Add opaque struct spi_slave for controller-specific data associated
with a slave.
- Add spi_claim_bus() and spi_release_bus()
- Add spi_free_slave()
- spi_setup() is now called spi_setup_slave() and returns a
struct spi_slave
- soft_spi now supports four SPI modes (CPOL|CPHA)
- Add bus parameter to spi_setup_slave()
- Convert the new i.MX32 SPI driver
- Convert the new MC13783 RTC driver
Changed in v2:
- Convert the mpc8xxx_spi driver and the mpc8349emds board to the
new API.

This patch adds a configurable flash auto protection list that can be used
to make U-Boot protect flash regions in flash_init().
The idea has been discussed on the u-boot mailing list starting
on Nov 18th, 2007.
Even this patch brings a new feature it is used as a bugfix for 4xx
platforms where flash_init() does not completely protect the
monitor's flash range in all situations.
U-Boot protects the flash range from CFG_MONITOR_BASE to
(CFG_MONITOR_BASE + monitor_flash_len - 1) by default. This does not
include the reset vector at 0xfffffffc.
Example:
#define CFG_FLASH_AUTOPROTECT_LIST {{0xfff80000, 0x80000}}
This config option will auto protect the last 512k of flash that
contains the bootloader on board like APC405 and PMC405.

Some NOR flash chip from Spansion, for example, the s29ws-n MirrorBit
series require different addresses for buffered write commands. Define a
configuration option to support buffered writes on those chips. A more
elegant solution would be to automatically detect those chips by parsing
their CFI records, but that would require introduction of a fixup table
into the cfi_flash driver.

This patch makes SPARC/LEON processors able to read and write
to the SMC91111 chip using the chip external I/O bus of the memory
controller. This patchs defines the standard in and out macros
expected by the SMC9111 driver.
To access that I/O bus one must set up the memory controller
(MCTRL or FTMCTRL) correctly. It is assumed that the user sets
up this correctly when the other MCTRL parameters are set up. It
can be set up from the board configuration header file.

SPARC has implemented __raw_readq, it reads 64-bit from any 32-bit address.
SPARC CPUs implement flash_read64 which calls __raw_readq.
For current SPARC architectures (LEON2 and LEON3) each read from the
FLASH must lead to a cache miss. This is because FLASH can not be set
non-cacheable since program code resides there, and alternatively disabling
cache is poor from performance view, or doing a cache flush between each
read is even poorer.
Forcing a cache miss on a SPARC is done by a special instruction "lda" -
load alternative space, the alternative space number (ASI) is processor
implementation spcific and can be found by including <asm/processor.h>.
