2012-05-15net: move bootfile init into eth_initializeMike Frysinger
All arches init this the same way, so move the logic into the core net code to avoid duplicating it everywhere else. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Reviewed-by: Joe Hershberger <joe.hershberger@ni.com>
2012-05-15net: punt bd->bi_ip_addrMike Frysinger
This field gets read in one place (by "bdinfo"), and we can replace that with getenv("ipaddr"). After all, the bi_ip_addr field is kept up-to-date implicitly with the value of the ipaddr env var. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Reviewed-by: Joe Hershberger <joe.hershberger@ni.com>
2012-01-04x86: Convert board_init_f_r to a processing loopGraeme Russ
Create an init function array for board_init_f_r - This finalises the migration to a purely array based initialisation mechanism Also tweak a few comments while we are at it so everything is 'correct' -- Changes for v2: - Renamed to a more apt name - Fix bug in set_reloc_flag_r - Re-instate gd->flags = boot_flags; in board_init_f - Added commit message
2012-01-04x86: Split init functions out of board.cGraeme Russ
This patch moves towards reducing board.c to simply a set of init cores for the three initialisation phases (Flash, Flash/RAM, and RAM), a set of three init function arrays and a init function array processing function
2012-01-04x86: Move relocation code out of board.cGraeme Russ
2012-01-04x86: Move setup_pcat_compatibility() out of board.cGraeme Russ
This function simply does not belong in board.c -- Changes for v2: - Added commit message
2012-01-04x86: Move do_go_exec() out of board.cGraeme Russ
-- Changes for v2: - None
2012-01-04x86: Allow cache before copy to RAMGraeme Russ
-- Changes for v2: - None
2012-01-04x86: Create weak init_cache() and default enable_caches() functionsGraeme Russ
-- Changes for v2: - Tweaked commit title
2012-01-04x86: Set GD_FLG_RELOC after entering in-RAM copy of U-BootGraeme Russ
-- Changes for v2: - None
2012-01-04x86: Use fs for global dataGraeme Russ
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
2012-01-04x86: Rework relocation calculationsGraeme Russ
This commit introduces no functional changes - It simply re-arranges the calculations so that adding to them in future commits will be cleaner -- Changes for v2: - Fixed typo in title - Added commit message
2012-01-04x86: Simplify Flash-to-RAM code execution transitionGraeme Russ
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
2012-01-04x86: Speed up copy-to-RAM and clear BSS operationsGraeme Russ
The implementations of memcpy and memset are now the optimised versions from glibc, so use them instead of simple copy loops -- Changes for v2: - Removed unneeded brackets

2011-11-29x86: Don't relocate symbols which point to things that aren't relocatedGabe Black
This change adds an upper bound for symbols which are fixed up after u-boot is relocated into RAM. This way portions that are left at their original location can be referred to without having to manually fix up any pointers. Signed-off-by: Gabe Black <gabeblack@chromium.org>
2011-11-29x86: Ensure IDT and GDT remain 16-byte aligned post relocationGraeme Russ
Some CPUs have strict alignment requirements for these tables Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
2011-11-29x86: Provide more configuration granularityGraeme Russ
Planned future ports requires more granularity for some options Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
2011-11-29cosmetic: checkpatch cleanup of arch/x86/lib/*.cGraeme Russ

2011-10-23x86: Use getenv_ulong() in place of getenv(), strtoulSimon Glass
This changes the board code to use the new getenv_ulong() function. Signed-off-by: Simon Glass <sjg@chromium.org>
2011-10-05net: drop !NET_MULTI codeMike Frysinger
This is long over due. All but two net drivers have been converted, but those have now been dropped. The only thing left to do is actually delete all references to NET_MULTI and code that is compiled when that is not defined. So here we scrub the core code.

2011-08-04Convert ISO-8859 files to UTF-8Albert ARIBAUD
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 <albert.u.boot@aribaud.net>
2011-07-28unify version_stringAndreas Bießmann
This patch removes the architecture specific implementation of version_string where possible. Some architectures use a special place and therefore we provide U_BOOT_VERSION_STRING definition and a common weak symbol version_string.
