This patchset add SPL support for the AT91SAM9G20 based taurus board,
and the AT91SAM9M10G45 based corvus board from siemens, and replaces
the at91bootstrap code.
The boot.bin which replaces the at91bootstrap image can created with
mkimage:
./tools/mkimage -T atmelimage -d spl/u-boot-spl.bin spl/boot.bin
For other SoC this step is done in one step ... should we add this
also for AT91 based boards?
For example add a "u-boot.at91" target in the Makefile?
This patchset is based on the common updates for the taurus
and corvus board:
Patchwork [U-Boot] arm, at91: add generic board support for the taurus and corvus board
http://patchwork.ozlabs.org/patch/395398/
(now in mainline)
Patchwork [U-Boot] arm, at91: add spi dataflash support for the taurus board
http://patchwork.ozlabs.org/patch/395400/
Changes in v3:

add comment from Bo shen
- ignore 80 characters length as Bo Shen and Adreas Biessmann suggested
- fix AT91_PMC_MCKR_CSS_MASK and AT91_PMC_MCKR_PRES_MASK
- make matrix_init weak, and add it in the taurus board code
- do not introduce ifdef mess for the differences between the SoCs,
instead use a seperate file for each SoC:
- for armv5 (arm926ejs, now at91 series), named it spl_at91.c,
- for armv7 (cortex-a5, now, sama5d3), named it spl_atmel.c
- move common code to arch/arm/cpu/at91-common/spl.c
Changes in v2:

- add comment from Jagan Teki:

instead define a default in the spi driver -> new patch for v2
- add Reviewed-by: Andreas Bie?mann <andreas.devel@googlemail.com>
- add comment from Andreas Biessmann:
rename "MPDDRC_CR_EBISHARE" to "MPDDRC_CR_DQMS_SHARED"
- add comment from scott wood:
move nand_erase_one into "include/nand.h" and rename it
to spl_nand_erase_one

move CONFIG_SYS_SPI_WRITE_TOUT into drivers/spi/atmel_spi.h
and define a default value. Delete this define in the board
config files, where it is possible (all boards use currently
the same value).

use the configure value for computing the ba_off value
not the value from the cr register. This leaded in a
wrong ram configuration on the upcoming corvus spl board
support.

- make matrix_init weak, and add it in the taurus board code
- do not introduce ifdef mess for the differences between the SoCs,
instead use a seperate file for each SoC:
- for armv5 (arm926ejs, now at91 series), named it spl_at91.c,
- for armv7 (cortex-a5, now, sama5d3), named it spl_atmel.c
- move common code to arch/arm/cpu/at91-common/spl.c

From: Heiko Schocher @ 2014-10-31 7:31 UTC (permalink / raw)
To: u-boot
replaces the at91bootstrap code with SPL code.
make the spl image with:
./tools/mkimage -T atmelimage -d spl/u-boot-spl.bin spl/boot.bin
this writes the length of the spl image into the 6th
execption vector. This is needed from the ROM bootloader.

Changes in v3:
add comment from Bo Shen:
- make matrix_init weak, and add it in taurs board code
- add Reviewed-by from Bo Shen
Changes in v2:
- rename function "nand_erase_one" to "spl_nand_erase_one" as

Heiko is right, this is board specific and follows the current way to
implement spi for the atmel driver.
But Jagan is also right, we should move this code to the driver code
cause in fact it is parametrisation of generic code. Unfortunately this
change will blow up this series. I think we should consider this when
rewriting the atmel spi driver for dm, which will be done soon (but I
think not in this merge window). Jagan, is this Ok for you?
