x86: Fix DRAM bank size init with generic board

2013-04-15T23:26:09Z

The intention of the memory init code is that it should work the same with CONFIG_SYS_GENERIC_BOARD and without. This is tricky because dram_init() is called prior to relocation with generic board (matching other archs) and after relocation without generic board. Adjust the init sequence so that dram_init() is not called in the generic board case, which seems like the easiest fix for now. Also ensure that relocation addresses are still calculated.

x86: Move PCI init before SPI init

2013-03-19T15:45:37Z

It is possible that our PCI bus will provide the SPI controller, so change the init order to make this work. Signed-off-by: Simon Glass

Merge branch 'master' of git://git.denx.de/u-boot-arm

2013-03-18T18:37:18Z

Albert's rework of the linker scripts conflicted with Simon's making everyone use __bss_end. We also had a minor conflict over README.scrapyard being added to in mainline and enhanced in u-boot-arm/master with proper formatting.

x86: Enable generic board

2013-03-15T20:14:01Z

This will be used exclusively on x86, so enable it for the whole architecture. Signed-off-by: Simon Glass

x86: Enable generic board support

2013-03-15T20:14:00Z

This enables generic board support so that x86 boards can define CONFIG_SYS_GENERIC_BOARD. Signed-off-by: Simon Glass

x86: Use sections header to obtain link symbols

2013-03-15T20:14:00Z

These are defined in asm-generic/sections.h, so remove them from architecture-specific files. Signed-off-by: Simon Glass

Introduce generic pre-relocation board_f.c

2013-03-15T20:13:59Z

This file handles common pre-relocation init for boards which use the generic framework. It starts up the console, DRAM, performs relocation and then jumps to post-relocation init. Signed-off-by: Simon Glass Tested-by: Wolfgang Denk Acked-by: Wolfgang Denk

Change stub example to use asm-generic/sections.h

2013-03-15T20:13:58Z

We can use the declarations of __bss_start and _end from this header instead of declaring them locally. Signed-off-by: Simon Glass

Introduce generic link section.h symbol files

2013-03-15T20:13:58Z

We create a separate header file for link symbols defined by the link scripts. It is helpful to have these all in one place and try to make them common across architectures. Since Linux already has a similar file, we bring this in even though many of the symbols there are not relevant to us. Each architecture has its own asm/sections.h where symbols specifc to that architecture can be added. For now everything except AVR32 just includes the generic header. One change is needed in arch/avr32/lib/board.c to make this conversion work. Reviewed-by: Tom Rini (version 5) Signed-off-by: Simon Glass

Refactor linker-generated arrays

2013-03-12T22:28:40Z

Refactor linker-generated array code so that symbols which were previously linker-generated are now compiler- generated. This causes relocation records of type R_ARM_ABS32 to become R_ARM_RELATIVE, which makes code which uses LGA able to run before relocation as well as after. Note: this affects more than ARM targets, as linker- lists span possibly all target architectures, notably PowerPC.
