x86: Use fs for global data

2012-01-04T11:17:24Z

Use the base address of the 'F' segment as a pointer to the global data structure. By adding the linear address (i.e. the 'D' segment address) as the first word of the global data structure, the address of the global data relative to the 'D' segment can be found simply, for example, by: fs movl 0, %eax This makes the gd 'pointer' writable prior to relocation (by reloading the Global Desctriptor Table) which brings x86 into line with all other arches NOTE: Writing to the gd 'pointer' is expensive (but we only do it twice) but using it to access global data members (read and write) is still fairly cheap -- Changes for v2: - Rebased against changes made to patch #3 - Removed extra indent - Tweaked commit message

x86: Simplify Flash-to-RAM code execution transition

2012-01-04T11:17:20Z

Move the relocation offset calculation out of assembler and into C. This also paves the way for the upcoming init sequence simplification by adding the board_init_f_r flash to RAM transitional function -- Changes for v2: - Added commit message - Minor adjustment to new stack address comment

x86: Remove GDR related magic numbers

2012-01-04T10:05:09Z

-- Changes for v2: - Use an enum - Add defined for GDT size (previously added in patch 7) - Use X86_ namespace (as per Linux headers)

x86: Add multiboot header

2011-11-29T10:08:02Z

By adding a multiboot header, U-Boot can be loaded by GRUB2. Using GRUB2 to bootstrap U-Boot is useful for using an existing BIOS to get an initial U-Boot port up and running before implementing the low-level reset vector code, SDRAM init, etc. and overwriting the BIOS Signed-off-by: Graeme Russ

Convert ISO-8859 files to UTF-8

2011-08-04T21:34:02Z

There was a mix of UTF-8 and ISO-8859 files in the U-Boot source tree, which could cause issues with the patchwork review system. This commit converts all ISO-8859 files to UTF-8. Signed-off-by: Albert ARIBAUD

cleanup: Fix typos and misspellings in various files.
