[PATCH v6 0/3] Boot up with a splash picture configurable

by Wayne Xia

Patch 1 and 2 remains the same with V5, only patch 3 is new, it need the patch "Add "romfile" code to assist with extract integer config settings." applied. sorry for that previous patches got a bit mess about the versions, please have a look about this one. short description about patch 3: when it boot up, try discover the qemu' configuration about whether to show a brand picture, with out a menu followed. -- Best Regards Wayne Xia mail:xiawenc@linux.vnet.ibm.com tel:86-010-82450803

[PATCH 0/8] SeaBIOS code to extract config parameters

by Kevin O'Connor

This patch series enables SeaBIOS to pull common config settings from CBFS (on coreboot) or fw_cfg (on QEmu). The series also converts several compile-time settings to this new dynamic system. I choose to place the file names in the "etc/" directory so that it is clear they are configuration settings. On coreboot, a user would do the following to enable a setting: /path/to/seabios/tools/encodeint.py boot-menu-wait 5500 ./build/cbfstool coreboot.rom add boot-menu-wait etc/boot-menu-wait raw ./build/cbfstool coreboot.rom print See the patch descriptions below for the six compile-time settings that are converted. -Kevin Kevin O'Connor (8): Add "romfile" code to assist with extract integer config settings. Replace CONFIG_BOOTMENU_WAIT with dynamic "etc/boot-menu-wait" file. Replace CONFIG_EXTRA_PCI_ROOTS with dynamic "etc/extra-pci-roots" file. Replace CONFIG_PS2_KEYBOARD_SPINUP with "etc/ps2-keyboard-spinup" file. Replace "CONFIG_OPTIONROMS_CHECKSUM" with "etc/optionroms-checksum" file. Replace CONFIG_S3_RESUME_VGA_INIT with "etc/s3-resume-vga-init" file. Replace CONFIG_SCREEN_AND_DEBUG with "etc/screen-and-debug" file.
