Various Kconfig fixes and improvements:
- Add helps texts to multiple user-visible Kconfig options. - Improve some menu and option names. - PAYLOAD_NONE should come before PAYLOAD_ELF, so that you scroll down (instead of up) when changing "no payload" to "ELF payload" (more intuitive, IMHO). - s/cbfs/cbfstool/. - Add some TODO items where needed. - Put GDB_STUB in a "Debugging" menu, no options should be top-level. There'll be more debug options later, I'm pretty sure. - Start converting help texts which are not user-visible to #-comments. - Re-order some options for more intuitive menus. - Set ARCH_X86 and ARCH_POWERPC to "default n", each boards selects them. - "Maximum reboot count" should proabably not be user-selectable, or at most if CONFIG_EXPERT (yet to be added) is enabled. It does definately not need its own "Misc options" menu. - Set PCI_ROM_RUN and VGA_ROM_RUN to "default y", most users will want to run option ROMs. Signed-off-by: Uwe Hermann <uwe@hermann-uwe.de> Acked-by: Uwe Hermann <uwe@hermann-uwe.de> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@4734 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
