x86: Remove legacy board init code

2013-05-13T20:33:20Z

Since we use CONFIG_SYS_GENERIC_BOARD on x86, we don't need this anymore. Signed-off-by: Simon Glass Acked-by: Graeme Russ

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

x86: Support relocation of FDT on start-up

2013-03-04T23:57:47Z

With CONFIG_OF_CONTROL we may have an FDT in the BSS region. Relocate it up with the rest of U-Boot to keep the rest of memory free. Signed-off-by: Simon Glass

x86: Add an __end symbol to signal the end of the U-Boot binary

2013-03-04T23:57:38Z

With this symbol we can easy append something (e.g. an FDT) to the U-Boot binary and access it from within U-Boot. Signed-off-by: Simon Glass

x86: Add function to get top of usable ram

2013-03-04T23:56:46Z

The memory layout calculations are done in calculate_relocation_address(), and coreboot has its own version of this function. But in fact all we really need is to set the top of usable RAM, and then the base version will work as is. So instead of allowing the whole calculate_relocation_address() function to be replaced, create board_get_usable_ram_top() which can be used by a board to specify the top of the area where U-Boot relocations to.

x86: Add support for CONFIG_OF_CONTROL

x86: Make calculate_relocation_address an overridable function

2012-12-06T22:30:41Z

Different systems may have different mechanisms for picking a suitable place to relocate U-Boot to. Signed-off-by: Gabe Black Signed-off-by: Simon Glass

x86: Reorder x86's post relocation memory layout

2012-12-06T22:30:41Z

This changes the layout in decreasing addresses from: 1. Stack 2. Sections in the image 3. Heap to 1. Sections in the image 2. Heap 3. Stack This allows the stack to grow significantly more since it isn't constrained by the other u-boot areas. More importantly, the generic memory wipe code assumes that the stack is the lowest addressed area used by the main part of u-boot. In the original layout, that means that u-boot tramples all over itself. In the new layout, it works. Signed-off-by: Gabe Black Signed-off-by: Simon Glass
