* Add support for the ASUS P4B266 boardUwe Hermann2008-05-221-0/+49
| | | | | | | | | | | | | | | Tested on actual hardware. This patch add an ich_gpio_raise() function which can be re-used by other board-specific funtions which need to raise GPIOs on ICHx southbridges. This also fixes bug #7, see http://tracker.coreboot.org/trac/coreboot/ticket/7, as it turned out the ICH2 (and other ICHx) code works fine.

* Support Pm49FL004/2 Block Locking RegistersNikolay Petukhov2008-05-175-58/+121
| | | | | | | | | | | | | | | | | | The PMC chips understand both LPC and FWH flash commands. When in FWH mode (MSR_DIVIL_BALL_OPT(0x51400015) = 0x00000f7d on 5536 boards) the Block Locking Registers by default lock the flash chip for write and erase - in addition to any chipset write protection. This patch adds unlock operations before Pm49FL004/2 write and erase, and it includes an svn mv pm49fl004.c pm49fl00x.c Thanks go to Nikolay for this patch.

The SST 39SF020 is completely incompatible with the 28SF040. No need for replacement. According to the data sheet, standard JEDEC commands will work and we have those commands in the tree already.

| | | | | | | | | | | | | | | | The generic jedec.c does not work for the ST M50FLW flash devices, because they need an unlock command first. For this reason, ST M50FLW support is moved to a new HW support module, because any change in jedec.c would bear the risk to cause problems with the already supported devices.

These ensures absolute data security of critical areas (BIOS boot block), e.g. against a sudden power off or a CPU hangup during flashing.
