From 78c733c2b737d0bfba8e9c614ab50a9dd04c8cc8 Mon Sep 17 00:00:00 2001 From: Patrick Georgi Date: Sat, 22 May 2010 15:07:15 +0000 Subject: [PATCH] Add tinybootblock support for broadcom/bcm5785. In the bootblock, 4MB of ROM are mapped instead of the default 1MB Signed-off-by: Patrick Georgi Acked-by: Myles Watson git-svn-id: svn://svn.coreboot.org/coreboot/trunk@5580 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1 --- src/southbridge/broadcom/bcm5785/Kconfig | 6 ++++++ .../broadcom/bcm5785/bcm5785_early_setup.c | 15 +-------------- .../broadcom/bcm5785/bcm5785_enable_rom.c | 14 ++++++++++++++ src/southbridge/broadcom/bcm5785/bootblock.c | 5 +++++ 4 files changed, 26 insertions(+), 14 deletions(-) create mode 100644 src/southbridge/broadcom/bcm5785/bcm5785_enable_rom.c create mode 100644 src/southbridge/broadcom/bcm5785/bootblock.c diff --git a/src/southbridge/broadcom/bcm5785/Kconfig b/src/southbridge/broadcom/bcm5785/Kconfig index c51dcb2b1..d72afd8d2 100644 --- a/src/southbridge/broadcom/bcm5785/Kconfig +++ b/src/southbridge/broadcom/bcm5785/Kconfig @@ -1,2 +1,8 @@ config SOUTHBRIDGE_BROADCOM_BCM5785 bool + select HAVE_HARD_RESET + +config BOOTBLOCK_SOUTHBRIDGE_INIT + string + default "southbridge/broadcom/bcm5785/bootblock.c" + depends on SOUTHBRIDGE_BROADCOM_BCM5785 diff --git a/src/southbridge/broadcom/bcm5785/bcm5785_early_setup.c b/src/southbridge/broadcom/bcm5785/bcm5785_early_setup.c index d448bf67c..62e004dac 100644 --- a/src/southbridge/broadcom/bcm5785/bcm5785_early_setup.c +++ b/src/southbridge/broadcom/bcm5785/bcm5785_early_setup.c @@ -4,20 +4,7 @@ */ #include -static void bcm5785_enable_rom(void) -{ - unsigned char byte; - device_t addr; - - /* Enable 4MB rom access at 0xFFC00000 - 0xFFFFFFFF */ - /* Locate the BCM 5785 SB PCI Main */ - addr = pci_locate_device(PCI_ID(0x1166, 0x0205), 0); // 0x0201? - - /* Set the 4MB enable bit bit */ - byte = pci_read_config8(addr, 0x41); - byte |= 0x0e; - pci_write_config8(addr, 0x41, byte); -} +#include "bcm5785_enable_rom.c" static void bcm5785_enable_lpc(void) { diff --git a/src/southbridge/broadcom/bcm5785/bcm5785_enable_rom.c b/src/southbridge/broadcom/bcm5785/bcm5785_enable_rom.c new file mode 100644 index 000000000..7d484d87c --- /dev/null +++ b/src/southbridge/broadcom/bcm5785/bcm5785_enable_rom.c @@ -0,0 +1,14 @@ +static void bcm5785_enable_rom(void) +{ + unsigned char byte; + device_t addr; + + /* Enable 4MB rom access at 0xFFC00000 - 0xFFFFFFFF */ + /* Locate the BCM 5785 SB PCI Main */ + addr = pci_locate_device(PCI_ID(0x1166, 0x0205), 0); // 0x0201? + + /* Set the 4MB enable bit bit */ + byte = pci_read_config8(addr, 0x41); + byte |= 0x0e; + pci_write_config8(addr, 0x41, byte); +} diff --git a/src/southbridge/broadcom/bcm5785/bootblock.c b/src/southbridge/broadcom/bcm5785/bootblock.c new file mode 100644 index 000000000..eab61a367 --- /dev/null +++ b/src/southbridge/broadcom/bcm5785/bootblock.c @@ -0,0 +1,5 @@ +#include "bcm5785_enable_rom.c" + +static void bootblock_southbridge_init(void) { + bcm5785_enable_rom(); +} -- 2.25.1
