Hello,
Attached patch adds support for tinybootblock on VT8237* to decode whole flash
independent of strapping, making larger flashes work again (as it was in
pre-tiny bootblock era)
Signed-off-by: Rudolf Marek <r.marek at assembler.cz>
I had a strange problem:
#include <arch/io.h>
#include <arch/romcc_io.h>
#include <device/pci_ids.h>
static void bootblock_southbridge_init(void) {
device_t dev;
/* Power management controller */
dev = pci_locate_device(PCI_ID(PCI_VENDOR_ID_VIA,
PCI_DEVICE_ID_VIA_VT8237R_LPC), 0);
if (dev == PCI_DEV_INVALID) {
/* Power management controller */
dev = pci_locate_device(PCI_ID(PCI_VENDOR_ID_VIA,
PCI_DEVICE_ID_VIA_VT8237S_LPC), 0);
if (dev == PCI_DEV_INVALID)
return;
}
pci_write_config8(dev, 0x41, 0x7f);
}
did not reach the pci write for some reason. This code is a copy from
enable_rom_decode() so it should work.
Thanks,
Rudolf
