* x86: Refactor the zboot innards so they can be reused with a vboot imageGabe Black2011-12-19-3/+5
| | | | | | | | | | | | | | | 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.

* x86: Add support for booting Linux using the 32 bit boot protocolGabe Black2011-12-19-2/+7
| | | | | | | | | 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>
* x86: Clean up the x86 zimage code in preparation to extend itGabe Black2011-12-19-21/+0
| | | | | | | | 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>
* x86: Import code from coreboot's libpayload to parse the coreboot tableGabe Black2011-12-19-0/+341
| | | | | | | | | | | | | 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>
* x86: Import the glibc memset implementationGabe Black2011-11-29-1/+1
| | | | | | | 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>

* console: Implement pre-console bufferGraeme Russ2011-10-05-0/+3
| | | | | | | | | | | | | 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.
* Convert ISO-8859 files to UTF-8Albert ARIBAUD2011-08-04-11/+11
| | | | | | | | 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>
