[U-Boot] [PATCH 1/2] dm: core: Add uclass_first_device_err() to return a valid device
by Simon Glass 13 Mar '16

13 Mar '16

A common pattern is to call uclass_first_device() and then check if it actually returns a device. Add a new function which does this, returning an error if there are no devices in that uclass.

[U-Boot] [PATCH v4] x86: baytrail: Configure FSP UPD from device tree
by Andrew Bradford 12 Mar '16

12 Mar '16

From: Andrew Bradford <andrew.bradford(a)kodakalaris.com> Allow for configuration of FSP UPD from the device tree which will override any settings which the FSP was built with itself. Modify the MinnowMax and BayleyBay boards to transfer sensible UPD settings from the Intel FSPv4 Gold release to the respective dts files, with the condition that the memory-down parameters for MinnowMax are also used. Signed-off-by: Andrew Bradford <andrew.bradford(a)kodakalaris.com> --- Changes from v3: - Fix small typographical issues (lowercase hex numbers, grammar, etc), no functional changes. Changes from v2: - Switch to using booleans in dts, where appropriate. - Add Bayley Bay dts modifications. - Clarify docs to show bool versus int properties. - Include enable-igt property from FSPv4. Changes from v1: - Use "-" rather than "_" in dt property names. - Use "Bay Trail" for the formal name of the Intel product family. - Use an "fsp," prefix for dt property names for clarity. - Fix minor code indentation issues. - Create a dt subnode for the memory-down-params. - Clarify documentation that dt overrides the FSP's config, so we don't use booleans. arch/x86/cpu/baytrail/fsp_configs.c | 167 +++++++++++++++++---- arch/x86/dts/bayleybay.dts | 40 +++++ arch/x86/dts/minnowmax.dts | 58 +++++++ .../misc/intel,baytrail-fsp.txt | 158 +++++++++++++++++++ include/fdtdec.h | 2 + lib/fdtdec.c | 2 + 6 files changed, 397 insertions(+), 30 deletions(-) create mode 100644 doc/device-tree-bindings/misc/intel,baytrail-fsp.txt diff --git a/arch/x86/cpu/baytrail/fsp_configs.c b/arch/x86/cpu/baytrail/fsp_configs.c index 86b6926..ba56ebb 100644 --- a/arch/x86/cpu/baytrail/fsp_configs.c +++ b/arch/x86/cpu/baytrail/fsp_configs.c @@ -1,14 +1,18 @@ /* * Copyright (C) 2013, Intel Corporation * Copyright (C) 2014, Bin Meng <bmeng.cn(a)gmail.com> + * Copyright (C) 2015, Kodak Alaris, Inc * * SPDX-License-Identifier: Intel */ #include <common.h> +#include <fdtdec.h> #include <asm/arch/fsp/azalia.h> #include <asm/fsp/fsp_support.h> +DECLARE_GLOBAL_DATA_PTR; + /* ALC262 Verb Table - 10EC0262 */ static const uint32_t verb_table_data13[] = { /* Pin Complex (NID 0x11) */ @@ -116,41 +120,144 @@ const struct pch_azalia_config azalia_config = { .reset_wait_timer_us = 300 }; +/** + * Override the FSP's UPD. + * If the device tree does not specify an integer setting, use the default + * provided in Intel's Baytrail_FSP_Gold4.tgz release FSP/BayleyBayFsp.bsf file. + */ void update_fsp_upd(struct upd_region *fsp_upd) { struct memory_down_data *mem; + const void *blob = gd->fdt_blob; + int node; - /* - * Configure everything here to avoid the poor hard-pressed user - * needing to run Intel's binary configuration tool.

[U-Boot] [PATCH v2 0/3] x86: Support booting SeaBIOS
by Bin Meng 11 Mar '16

This is the initial attempt to support booting SeaBIOS from U-Boot. This is tested: - On Intel Crown Bay board with a PCIe graphics card, booting SeaBIOS then chain-loading a GRUB on a USB drive, then Linux kernel finally. - On QEMU x86 target with U-Boot chain-loading SeaBIOS to install/boot a Windows XP OS. This series is available on u-boot-x86/seabios-working. Previous RFC patch @ http://patchwork.ozlabs.org/patch/523764/ Changes in v2: - Drop patches which were already applied - Add more detailed information for testing QEMU/SeaBIOS (eg: how to create 'disk.img') Bin Meng (3): x86: Support booting SeaBIOS x86: qemu: Enable ACPI table generation by default x86: Document how to play with SeaBIOS arch/x86/Kconfig | 10 ++++++++ arch/x86/include/asm/tables.h | 3 +++ arch/x86/lib/tables.c | 15 ++++++++++++ configs/qemu-x86_defconfig | 1 + doc/README.x86 | 57 +++++++++++++++++++++++++++++++++++++++++-- 5 files changed, 84 insertions(+), 2 deletions(-) -- 1.8.2.1

[U-Boot] [PATCH v1 1/3] fastboot: OUT transaction length must be aligned to wMaxPacketSize
by Dileep Katta 11 Mar '16

11 Mar '16

OUT transactions must be aligned to wMaxPacketSize for each transfer, or else transfer will not complete successfully. This patch modifies rx_bytes_expected to return a transfer length that is aligned to wMaxPacketSize. Note that the value of ep->desc->wMaxPacketSize and ep->maxpacket may not be the same value, and it is the value of ep->desc->wMaxPacketSize that should be used for alignment.

[U-Boot] [PATCH] rockchip: rk3288: correct sdram setting
by Chris Zhong 10 Mar '16

10 Mar '16

The DMC driver in v3.14 kernel[0] get the ddr setting from PMU_SYS_REG2, and it expects uboot to store the value using a same protocol. But now the ddr setting value is different with DMC, so if you enable the DMC, system would crash in kernel. Correct the sdram setting here, according to the requirements of kernel.

[U-Boot] [RFC] armv8: layerscape: Add support of u-boot device tree fix-up
by Prabhakar Kushwaha 09 Mar '16

09 Mar '16

There is a requirement of u-boot dts fix-up before it is being consumed by u-boot. NXP's SoC LS2085A, LS2080A and LS2088A are almost same except variation in ARM core where LS2085A/LS2080A has A57 and LS2088A has A72. These SoCs will be placed on common LS2085ARDB platform. So instead of maintaining defferent device tree per SoC, fix-up dts before being used by u-boot.
