[U-Boot] [PATCH v2 0/11] avr32: add generic board

[U-Boot] [PATCH v2 0/11] avr32: add generic board

[Andreas Bießmann]

This is the first attempt to add generic board support to avr32 architecture. It
has at least one relevant part for other manual reloc architectures.

This series is currently runtime tested on grasshhopper and atstk1002.

Andreas Bie?mann

BEWARE:
The 'common/board_f: factor out reserve_stacks' patch is only partly compile
tested for some ppc/arm boards yet.

Changes in v2:
- new since v1
- new since v1
- provide as extra patch, remove from avr32 generic board support
- remove bootparams allocation, provide as extra patch
- use the else path in setup_mon_len()
- provide arch_reserve_stacks() for avr32
- use the newly introduced dram_init()

Changes in v1:
- new since RFC
- new since RFC
- add timer_init in board_r
- remove extern declaration of mmu_init_r()
- new since RFC

Andreas Bie?mann (11):
  avr32: use dlmalloc for DMA buffers
  avr32: rename cpu_init() -> arch_cpu_init()
  avr32: factor out cpu_mmc_init()
  avr32: rename mmu.h definitions
  avr32: convert to dram_init()
  common/board_f: factor out reserve_stacks
  common/board_r: manual relocation for cmd table
  common/board_r: allocate bootparams
  avr32: add generic board support
  grasshopper: enable generic board
  atstk1002: enable generic board

[U-Boot] [PATCH v2 03/11] avr32: factor out cpu_mmc_init()

[Andreas Bießmann]

cpu_mmc_init() is required by the init sequence to have a working MMC interface
on avr32. This will not be included in the binary if we omit the avr32 board.c
when building the generic board.

[U-Boot] [PATCH v2 06/11] common/board_f: factor out reserve_stacks

[Andreas Bießmann]

Require each architecture to provide an arch_reserve_stacks() function to
setup the required stacks for the architecture.

This patch is _not_ fully compile tested for all ppc/arm boards!

[U-Boot] [PATCH v2 09/11] avr32: add generic board support

[Andreas Bießmann]

Signed-off-by: Andreas Bie?mann <andreas.devel@googlemail.com>
---
This version still has the mmu_init_r() in common/board_r. Removing this now is
not that easy ... I'd love to get it in as is and change it later to the
board_init_f_r() sequence.

Changes in v2:
- remove bootparams allocation, provide as extra patch
- use the else path in setup_mon_len()
- provide arch_reserve_stacks() for avr32
- use the newly introduced dram_init()

Changes in v1:
- add timer_init in board_r
- remove extern declaration of mmu_init_r()

It's nice to see this clean-up.

This does force every arch to provide this function. For some
architectures I suspect that this will be enough:

       gd->start_addr_sp -= 16;
       gd->start_addr_sp &= ~0xf;

So I think it might be better to put that code in reserve_stacks() and
then call a weak arch_reserve_stacks() after that.

Should add a little more detail here:

On entry gd->start_addr_sp is pointing to the suggested top of the stack
On exit this should be updated to the position of the stack. The stack
pointer will be set to this later
gd->irq_sp should be set if this is needed by the arch.

also @return 0 if no error
