2012-08-09global_data: unify global flag definesMike Frysinger
All the global flag defines are the same across all arches. So unify them in one place, and add a simple way for arches to extend for their needs. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
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: Create weak init_cache() and default enable_caches() functionsGraeme Russ
-- Changes for v2: - Tweaked commit title
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: 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: Remove GDR related magic numbersGraeme Russ
-- Changes for v2: - Use an enum - Add defined for GDT size (previously added in patch 7) - Use X86_ namespace (as per Linux headers)
2012-01-02x86: Import glibc memcpy implementationGraeme Russ
Taken from glibc version 2.14.90 -- Changes for v2: - None
2011-12-19x86: Refactor the zboot innards so they can be reused with a vboot imageGabe Black
If vboot successfully verifies a kernel, it will leave it in place and basically ready to boot. The zeropage table which is part of the x86 boot protocol is at the end of the kernel, though, instead of the beginning, and because the image is already in place there's no need to copy it around. This change refactors the code which implements the zboot command so that the configuration of the zeropage table and loading the pieces of the kernel into memory are done separately. Also, because the command line goes before the zeropage table in vboot which is somewhat incompatible with the normal protocol, where to put the command line is a now a parameter instead of being hard coded.

2011-12-19x86: Add support for booting Linux using the 32 bit boot protocolGabe Black
This change conditionally modifies the zboot command so that it can use the 32 bit boot protocol. This is necessary because the 16 bit realmode entry point assumes that it can call BIOS services which neither coreboot nor u-boot provide. Signed-off-by: Gabe Black <gabeblack@chromium.org>
2011-12-19x86: Clean up the x86 zimage code in preparation to extend itGabe Black
This change cleans up some formatting issues in the zimage handling code, and converts it from using offsets added to a base pointer to using the available structure definitions which were already being included. Signed-off-by: Gabe Black <gabeblack@chromium.org>
2011-12-19x86: Import code from coreboot's libpayload to parse the coreboot tableGabe Black
This change also forces the lib_sysinfo structure to be in the .data section. Otherwise it ends up in the .bss section. U-boot assumes that it doesn't need to copy it over during relocation, and instead fills that whole section with zeroes. If we really were booting from ROM that would be appropriate, but we need some information from the coreboot tables (memory size) before then and have to fill that structure before relocation. We skirt u-boot's assumption by putting this in .data where it assumes there is still read only but non-zero data. Signed-off-by: Gabe Black <gabeblack@chromium.org>
2011-11-29x86: Import the glibc memset implementationGabe Black
The new implementation is about twice as fast as the old. This is from glibc-2.14, sysdeps/i386/memset.c. Signed-off-by: Gabe Black <gabeblack@chromium.org>

2011-10-05console: Implement pre-console bufferGraeme Russ
Allow redirection of console output prior to console initialisation to a temporary buffer. To enable this functionality, the board (or arch) must define: - CONFIG_PRE_CONSOLE_BUFFER - Enable pre-console buffer - CONFIG_PRE_CON_BUF_ADDR - Base address of pre-console buffer - CONFIG_PRE_CON_BUF_SZ - Size of pre-console buffer (in bytes) The pre-console buffer will buffer the last CONFIG_PRE_CON_BUF_SZ bytes Any earlier characters are silently dropped.
