[U-Boot] [PATCH v3 0/8] x86: qemu: add fw_cfg interface support for qemu-x86 targets
by Miao Yan 30 Dec '15

30 Dec '15

The fw_cfg interface provided by QEMU allow guests to retrieve various information about the system, e.g. cpu number, variaous firmware data, kernel setup, etc. The fw_cfg interface can be accessed through 3 IO ports (on x86), using x86 in/out instructions. - 0x510: select configuration items to access - 0x511: reading this port will return data selected in 0x510 - 0x514: this can be used to detect if DMA interface is available If fw_cfg DMA interface is available, it can be used to accelerate accesses. This patchset adds the following supports for qemu-x86 targets: + the fw_cfg driver itself + add a U-Boot command 'fw' to support direct accessing kernel informtion from fw_cfg interface, this saves the time of loading them from hard disk or network again, through emulated devices. + use fw_cfg to get cpu number at runtime, so smp boot no longer relies on the cpu node hard-coded in dts files. Changes in v2: - rebase to u-boot-x86/next - various cleanups Changes in v3: - fix an error in do_qemu_fw() Miao Yan (8): x86: qemu: add fw_cfg support x86: qemu: add a cpu uclass driver for qemu target x86: fix a typo in function name x86: use actual CPU number for allocating memory x86: qemu: add qemu_fwcfg_fdt_fixup() x86: qemu: fix up cpu node in device tree x86: reserve more spaces for dtb x86: qemu: add documentaion for the fw_cfg interface arch/x86/cpu/mp_init.c | 12 +- arch/x86/cpu/qemu/Makefile | 2 +- arch/x86/cpu/qemu/cpu.c | 57 ++++++++ arch/x86/cpu/qemu/fw_cfg.c | 306 +++++++++++++++++++++++++++++++++++++++ arch/x86/cpu/qemu/fw_cfg.h | 108 ++++++++++++++ arch/x86/cpu/qemu/qemu.c | 7 + arch/x86/dts/Makefile | 2 +- arch/x86/dts/qemu-x86_i440fx.dts | 19 +-- arch/x86/dts/qemu-x86_q35.dts | 19 +-- doc/README.x86 | 36 ++++- 10 files changed, 521 insertions(+), 47 deletions(-) create mode 100644 arch/x86/cpu/qemu/cpu.c create mode 100644 arch/x86/cpu/qemu/fw_cfg.c create mode 100644 arch/x86/cpu/qemu/fw_cfg.h -- 1.9.1

[U-Boot] [PATCH re-send v6 00/17] device model bring-up of ti-qspi on dra72, dra74 and am437x-sk evm
by Mugunthan V N 30 Dec '15

30 Dec '15

Resending the patches as I have missed 01/17 patch while sending v6 series This patch series enables ti_qspi to adopt driver model. This has been tested on dra72, dra74 and am437x-sk evms (logs [1]). Also pushed a branch for testing [2] This patch series is based on u-boot-spi/next and a fix for Macronix flash Quad Enable as per the comments in thread [3].

Changes from Initial version: * Split "prepare driver for DM conversion" for easier review * added memory map mode to the driver * Fixed the cosmetic reviews from Simon * Modified the dev_get_addr_index to adopt OF_TRANSULATE as well and also removed code duplicate. * Added compatibles for spi flashed found in DRA7xx and AM437x SK Mugunthan V N (17): drivers: spi: ti_qspi: do not hard code chip select for memory map configuration drivers: spi:ti_qspi: change ti_qspi_slave to ti_qspi_priv for driver model conversion drivers: spi: ti_qspi: prepare driver for DM conversion dm: core: Add a new api to get indexed device address spi: Add support for dual and quad mode dra7xx_evm: qspi: do not define DM_SPI and DM_SPI_FLASH for spl dts: dra7: add spi alias for qspi drivers: spi: ti_qspi: convert driver to adopt device driver model arm: dts: dra7: add qspi register maps for memory map and control module arm: dts: am437x-gp-evm: add spi-flash comaptible for flash arm: dts: dra7-evm: add spi-flash comaptible for flash arm: dts: dra72-evm: add spi-flash comaptible for flash defconfig: dra72_evm: enable spi driver model defconfig: dra74_evm: enable spi driver model am43xx_evm: qspi: do not define DM_SPI and DM_SPI_FLASH for spl arm: dts: am4372: add qspi register maps for memory map defconfig: am437x_sk_evm: enable spi driver model arch/arm/dts/am4372.dtsi | 5 +- arch/arm/dts/am437x-sk-evm.dts | 2 +- arch/arm/dts/dra7-evm.dts | 2 +- arch/arm/dts/dra7.dtsi | 8 +- arch/arm/dts/dra72-evm.dts | 2 +- configs/am437x_sk_evm_defconfig | 3 + configs/dra72_evm_defconfig | 2 + configs/dra74_evm_defconfig | 2 + drivers/core/device.c | 31 ++- drivers/spi/spi-uclass.c | 31 +++ drivers/spi/ti_qspi.c | 524 ++++++++++++++++++++++++++++------------ include/configs/am43xx_evm.h | 2 + include/configs/dra7xx_evm.h | 5 + include/dm/device.h | 11 + include/spi.h | 4 + 15 files changed, 469 insertions(+), 165 deletions(-) -- 2.7.0.rc1.5.gf3adf45

[U-Boot] [RFC] igep00x0: UBI everywhere but SPL
by Ladislav Michl 30 Dec '15

30 Dec '15

This patch converts IGEP board to use UBI volumes for environment, u-boot, kernel... With exception of first four sectors with SPL loaded by SoC boot ROM whole NAND is UBI managed. I misused BOOT_DEVICE_BOARD, which is probably not briliant idea, but works well enough. Also code it too big, so I dropped CONFIG_SPL_EXT_SUPPORT to make it fit. It is meant more likely as a test of Thomas' patch, so more people can play with that. Thanks to Marek Vasut for pointing me to Thomas' work and arguing so well towards UBI that I had no other choice than giving it a try. --- diff --git a/arch/arm/include/asm/arch-omap3/spl.h b/arch/arm/include/asm/arch-omap3/spl.h index a31b4ea..ebac396 100644 --- a/arch/arm/include/asm/arch-omap3/spl.h +++ b/arch/arm/include/asm/arch-omap3/spl.h @@ -14,9 +14,10 @@ #define BOOT_DEVICE_MMC2 0x05 #define BOOT_DEVICE_MMC1 0x06 #define BOOT_DEVICE_XIPWAIT 0x07 -#define BOOT_DEVICE_MMC2_2 0x08 +#define BOOT_DEVICE_MMC2_2 0x08 #define BOOT_DEVICE_UART 0x10 #define BOOT_DEVICE_USB 0x11 +#define BOOT_DEVICE_BOARD 0xffffffff #define MMC_BOOT_DEVICES_START BOOT_DEVICE_MMC2 #define MMC_BOOT_DEVICES_END BOOT_DEVICE_MMC1 diff --git a/board/isee/igep00x0/igep00x0.c b/board/isee/igep00x0/igep00x0.c index e2fce50..4c4394f 100644 --- a/board/isee/igep00x0/igep00x0.c +++ b/board/isee/igep00x0/igep00x0.c @@ -10,6 +10,9 @@ #include <ns16550.h> #include <twl4030.h> #include <netdev.h> +#include <nand.h> +#include <ubispl.h> +#include <spl.h> #include <asm/gpio.h> #include <asm/io.h> #include <asm/arch/mem.h> @@ -212,3 +215,64 @@ int board_eth_init(bd_t *bis) #endif } #endif + +#ifdef CONFIG_SPL_OS_BOOT +int spl_start_uboot(void) +{ + /* break into full u-boot on 'c' */ + if (serial_tstc() && serial_getc() == 'c') + return 1;
