[U-Boot] buildman for sandbox
by Joe Hershberger 13 Mar '16

13 Mar '16

Hi Simon, Is there a way to make buildman compile sandbox with a non-system tool chain? I've tried creating an alias from sandbox to i386 and removing the "root" entry. It then simply claims not to have a sandbox tool chain. Thanks, -Joe

[U-Boot] [PATCH 0/2] Revert changes to __of_translate_address()
by Przemyslaw Marczak 13 Mar '16

13 Mar '16

Globally enabled CONFIG_OF_TRANSLATE causes, that function dev_get_addr() returns a different result for a node with: 'size-cells = <0>'. The above change, breaks the Exynos boards for a long time, because of GPIO driver, which uses the fdt in a non standard way. After sending few approaches with adding support for that case, the one was appllied for a temporary fix for the release: "fdt: fix address cell count checking in fdt_translate_address()" However, after discussion on the list, we found that this way can't be accepted because the function __of_translate_address() as a backend of dev_get_addr(), shouldn't be used for translating a non-MMIO addresses. Updating some device tree files with '#size-cells = 1' and by extending the 'reg' property by address length - fixes the problem.

The ICH GPIO driver does not work correctly at present. This series tidies things up and fixes a few bugs. One issue remaining is that reading from output GPIOs does not work - it always returns 0.

[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.
