2020-07-28arm: stm32mp: use correct weak function name spl_board_prepare_for_linuxPatrick Delaunay
Replace the function spl_board_prepare_for_boot_linux by the correct name of the weak function spl_board_prepare_for_linux defined in spl.h. This patch avoids warning with W=1 option: u-boot/arch/arm/mach-stm32mp/spl.c:150:6: warning: no previous prototype for ‘spl_board_prepare_for_boot_linux’ [-Wmissing-prototypes] Fixes: dc7e5f190de5 ("arm: stm32mp: activate data cache on DDR in SPL") Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com> Reviewed-by: Patrice Chotard <patrice.chotard@st.com>

2020-05-18common: Drop net.h from common headerSimon Glass
Move this header out of the common header. Network support is used in quite a few places but it still does not warrant blanket inclusion. Note that this net.h header itself has quite a lot in it. It could be split into the driver-mode support, functions, structures, checksumming, etc. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-05-14arm: stm32mp: activate data cache on DDR in SPLPatrick Delaunay
Activate cache on DDR to improve the accesses to DDR used by SPL: - CONFIG_SPL_BSS_START_ADDR - CONFIG_SYS_SPL_MALLOC_START Cache is configured only when DDR is fully initialized, to avoid speculative access and issue in get_ram_size(). Data cache is deactivated at the end of SPL, to flush the data cache and the TLB. Reviewed-by: Patrice Chotard <patrice.chotard@st.com> Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com>
2020-05-14arm: stm32mp: spl: update error management in board_init_fPatrick Delaunay
Call hang when an error is detected for probe of any driver needed for console or DDR init: clk, reset and pincontrol NB: previous behavior with a return in board_init_f() was not correct; DDR is not initialized and SPL execution can't continue Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com>

2020-04-22spl: mmc: Rename spl_boot_partition() to spl_mmc_boot_partition()Harald Seiler
This function is only relevant to the MMC driver so calling it spl_boot_partition() might be confusing. Rename it to spl_mmc_boot_partition() to make its purpose more clear (and bring it in line with spl_mmc_boot_mode()).

2020-04-22spl: mmc: Rename spl_boot_mode() to spl_mmc_boot_mode()Harald Seiler
The function's name is misleading as one might think it is used generally to select the boot-mode when in reality it is only used by the MMC driver to find out in what way it should try reading U-Boot Proper from a device (either using a filesystem, a raw sector/partition, or an eMMC boot partition). Rename it to spl_mmc_boot_mode() to make it more obvious what this function is about.

2020-01-17common: Move hang() to the same header as panic()Simon Glass
At present panic() is in the vsprintf.h header file. That does not seem like an obvious choice for hang(), even though it relates to panic(). So let's put hang() in its own header.

2018-05-07SPDX: Convert all of our multiple license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have multiple licenses (in these cases, dual license) declared in the SPDX-License-Identifier tag. In this case we change from listing "LICENSE-A LICENSE-B" or "LICENSE-A or LICENSE-B" or "(LICENSE-A OR LICENSE-B)" to "LICENSE-A OR LICENSE-B" as per the Linux Kernel style document. Note that parenthesis are allowed so when they were used before we continue to use them. Reviewed-by: Fabio Estevam <fabio.estevam@nxp.com> Signed-off-by: Tom Rini <trini@konsulko.com>
2018-04-06stm32mp1: select boot device and partitionPatrick Delaunay
Bootrom loads SPL from SDCARD or eMMC according BootPin selection. Then SPL loads U-Boot on the same mmc device with the following predefined GPT partitioning: on SDCARD: gpt partitioning 1: SPL 2: SPL#2 3: U-Boot 4: bootable partition on eMMC: The 2 boot partitions are used for SPL (2 copy) boot1: SPL boot2: SPL#2 The user partition use gpt partitioning 1: U-Boot 2: bootable partition This patch select the correct SPL partition (3 for SDCARD on mmc0 and 1 for eMMC on mmc1) according the BootRom information saved in TAMP register and based on configuration flasg: - CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_PARTITION => for BOOT_DEVICE_MMC1 or mmc 0 in U-Boot - CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_PARTITION_MMC2 (new) => for BOOT_DEVICE_MMC2 or mmc 1 in U-Boot And the correct boot_targets is selected according the environment variables boot_device and boot_instance, with preboot command, to search the bootable partition with kernel on this device (generic distro support).
