Move default y configs out of arch/board Kconfig

2015-06-26T02:17:55Z

Some archs/boards specify their own default by pre-defining the config which causes the Kconfig system to mix up the order of the configs in the defconfigs... This will cause merge pain if allowed to proliferate. Remove the configs that behave this way from the archs. A few configs still remain, but that is because they only exist as defaults and do not have a proper Kconfig entry. Those appear to be: SPIFLASH DISPLAY_BOARDINFO Signed-off-by: Joe Hershberger [trini: rastaban, am43xx_evm_usbhost_boot, am43xx_evm_ethboot updates, drop DM_USB from MSI_Primo81 as USB_MUSB_SUNXI isn't converted yet to DM] Signed-off-by: Tom Rini

x86: gpio: add pinctrl support from the device tree

2015-06-04T09:32:08Z

Every pin can be configured now from the device tree. A dt-bindings has been added to describe the different property available. Change-Id: I1668886062655f83700d0e7bbbe3ad09b19ee975 Signed-off-by: Gabriel Huau Acked-by: Simon Glass

x86: baytrail: pci region 3 is not always mapped to end of ram

2015-06-04T09:03:18Z

Baytrail physically maps the first 2 GB of SDRAM from 0x0 to 0x7FFFFFFF and additional SDRAM is mapped from 0x100000000 and up. There is a physical memory hole from 0x80000000 to 0xFFFFFFFF for other uses. Because of this, PCI region 3 should only try to use up to the amount of SDRAM or 0x80000000, which ever is less.

x86: qemu: Implement PIRQ routing

2015-06-04T09:03:18Z

Support QEMU PIRQ routing via device tree on both i440fx and q35 platforms. With this commit, Linux booting on QEMU from U-Boot has working ATA/SATA, USB and ethernet. Signed-off-by: Bin Meng Acked-by: Simon Glass

x86: coreboot: Control I/O port 0xb2 writing via device tree

2015-06-04T09:03:18Z

Writing 0xcb to I/O port 0xb2 (Advanced Power Management Control) causes U-Boot to hang on QEMU q35 target. We introduce a config option in the device tree "u-boot,no-apm-finalize" under /config node if we don't want to do that. Signed-off-by: Bin Meng Acked-by: Simon Glass

x86: qemu: Create separate i440fx and q35 device trees

2015-06-04T09:03:18Z

Although the two qemu-x86 targets (i440fx and q35) share a lot in common, they still have something that cannot easily handled in one single device tree). Split to create two dedicated device tree files and make the i440fx be the default build target. Signed-off-by: Bin Meng Acked-by: Simon Glass

x86: kconfig: Make FSP_TEMP_RAM_ADDR depend on HAVE_FSP

2015-06-04T09:03:17Z

FSP_TEMP_RAM_ADDR should only be visible when HAVE_FSP is on. Signed-off-by: Bin Meng Acked-by: Simon Glass

x86: qemu: Adjust VGA initialization

2015-06-04T08:39:40Z

As VGA option rom needs to run at C segment, although QEMU PAM emulation seems to only guard E/F segments, for correctness, move VGA initialization after PAM decode C/D/E/F segments. Also since we already tested QEMU targets to differentiate I440FX and Q35 platforms, change to locate the VGA device via hardcoded b.d.f instead of dynamic search for its vendor id & device id pair.

x86: qemu: Enable legacy IDE I/O ports decode

2015-06-04T08:39:39Z

QEMU always decode legacy IDE I/O ports on PIIX chipset. However Linux ata_piix driver does sanity check to see whether legacy ports decode is turned on. To make Linux ata_piix driver happy, turn on the decode via IDE_TIMING register. Signed-off-by: Bin Meng Acked-by: Simon Glass
