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
filesystems.
This patch is tested on two custom boards with PPC and ARM
processors running YAFFS in U-Boot and Linux using gcc-4.1.2
cross compilers.
MAKEALL ppc/arm has some issues:
* DOC/OneNand/nand_spl is not building (I have not tried porting
these parts, and since I do not have any HW and I am not familiar
with this code/HW I think its best left to someone else.)
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:
cpu/ppc4xx/ndfc.c
cpu/arm926ejs/davinci/nand.c
board/delta/nand.c
board/zylonite/nand.c

While locally preparing some U-Boot patches for ARM based OMAP3 boards, some
using OneNAND and some using NAND, we found some differences in OneNAND and
NAND command address handling.
As this might confuse users (it already confused us), we like to align OneNAND
and NAND address handling.
The issue is that cmd_onenand.c subtracts the onenand base address from the
addresses you type into the u-boot command line so, unlike nand, you can't
use addresses relative to the start of the onenand part e.g. this won't work:
onenand read 82000000 280000 400000
you have to use:
onenand read 82000000 20280000 400000
Looking at recent git, the only board currently using OneNAND is Apollon, and
for this the OneNAND base address is 0 (apollon.h)
#define CFG_ONENAND_BASE 0x00000000
so patch below won't break any existing boards and will align OneNAND and NAND
handling on boards where OneNAND base address is != 0.

U-Boot allows for configurable prompt strings using the
CONFIG_AUTOBOOT_PROMPT resp. CONFIG_MENUPROMPT definitions. So far,
the assumption was that any such user defined problts would contain
exactly one "%d" format specifier. But some boards did not.
To allow for flexible boot prompts without adding too complex code we
now allow to specify the whole list of printf() arguments in the user
definition. This is powerful, but requires a responsible user who
really understands what he is doing, as he needs to know for exanple
which variables are available in the respective context.

The origional code was using on odd reference to get to the first
real element in av_[]. The first two elements of the array are
not used for actual bins, but for house keeping. If we are more
explicit about how use the first few elements we can get rid of the
warnings:
dlmalloc.c: In function 'malloc_extend_top':
dlmalloc.c:1971: warning: dereferencing type-punned pointer will break strict-aliasing rules
dlmalloc.c:1999: warning: dereferencing type-punned pointer will break strict-aliasing rules
dlmalloc.c:2029: warning: dereferencing type-punned pointer will break strict-aliasing rules
...
The logic of how this code came to be is:
bin_at(0) = (char*)&(av_[2]) - 2*SIZE_SZ
SIZE_SZ is the size of pointer, and av_ is arry of pointers so:
bin_at(0) = &(av_[0])
Going from there to bin_at(0)->fd or bin_at(0)->size should be straight forward.

This way only the vectors need to get defined for new PPC's.

Turn off USB to prevent the host controller from writing to the
SDRAM while Linux is booting. This could happen, because the HCCA
(Host Controller Communication Area) lies within the SDRAM and the
host controller writes continously to this area (as busmaster!), for
example to increase the HccaFrameNumber variable, which happens
every 1 ms.
This is a slightly modified version of the patch in order to shutdown
USB when booting on all architectures.

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
