2023-05-02board: Add new Broadcom Northstar boardLinus Walleij
This adds a simple Northstar "BRCMNS" board to be used with the BCM4708x and BCM5301x chips. The main intention is to use this with the D-Link DIR-890L and DIR-885L routers for loading the kernel into RAM from NAND memory using the BCH-1 ECC and using the separately submitted SEAMA load command, so we are currently not adding support for things such as networking. The DTS file is a multiplatform NorthStar board, designed to be usable with several NorthStar designs by avoiding any particulars not related to the operation of U-Boot. If other board need other ECC for example, they need to create a separate DTS file and augment the code, but I don't know if any other users will turn up.

2023-05-02arm: Add support for the Broadcom Northstar SoCsLinus Walleij
The original Northstar is an ARM SoC series that comprise BCM4709x and BCM5301x and uses a dual-core Cortex A9, the global timer and a few other things. This series should not be confused with North Star Plus (NSP) which is partly supported by U-Boot already. The SoC is well supported by the Linux kernel and OpenWrt as it is used in many routers. Since we currently don't need any chip-specific quirks and can get the system up from just the device tree, a mach-* directory doesn't even need to be added, just some small Kconfig fragments.

2023-05-02arm: imx8m: remove unused and obsolete board_fix_fdt() in SOC contextHugo Villeneuve
It doesn't seem appropriate for arch/SOC to use a board-level functionality (CONFIG_OF_BOARD_FIXUP), because this prevents boards that need to do FDT fixup from using that feature. Also, this code is completely dead and useless (from comments by Rasmus Villemoes on the mailing list): - No in-tree imx8m-based board seems to set CONFIG_OF_BOARD_FIXUP - The nodes which that function wants to disable don't even exist in the U-Boot copy of imx8mp.dtsi. This code was introduced in commit 35bb60787b88. It seems to be some random import of code from downstream NXP U-Boot, with a commit message that makes no sense in upstream context.

2023-04-28sunxi: binman: Fix U-Boot offset when SPL is not 32 KiBSamuel Holland
On sunxi boards, SPL looks for U-Boot at a 32 KiB offset, unless SPL is larger than 32 KiB, in which case U-Boot immediately follows SPL. See the logic in spl_mmc_get_uboot_raw_sector() and spl_spi_load_image(). In two cases, the existing binman description mismatches the SPL code. For 64-bit boards, binman would place U-Boot immediately following SPL, even if SPL is smaller than 32 KiB. This can happen when SPL MMC support is disabled (i.e. when booting from SPI flash). In contrast, for 32-bit boards, binman would place U-Boot at 32 KiB, even if SPL is larger than that. This happens because the 'offset' property does not consider the size of previous entries. Fix both issues by setting a minimum size for the SPL entry, which exactly matches the logic in the SPL code. Unfortunately, this size must be provided as a magic number, since none of the relevant config symbols (SPL_PAD_TO, SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR, and SYS_SPI_U_BOOT_OFFS) are guaranteed to be defined in all cases.
