[U-Boot] [v2 PATCH 0/12] arm, at91, spl: add spl support for the taurus and corvus boards

[Heiko Schocher]

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)

Changes in v2:
  - rebased against d58a9451e7339ed4cf2b2627e534611f427fb791
  - spi, atmel: move CONFIG_SYS_SPI_WRITE_TOUT into common header
    new in v2
  - add comment from Jagan Teki:
    - remove spi_init_f() from board file
    - remove CONFIG_SYS_SPI_WRITE_TOUT from board config file
      instead define a default in the spi driver -> new patch for v2
  - add Reviewed-by: Andreas Bießmann <andreas.devel at 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
