[U-Boot] [PATCH] net: dm: fec: Fix regulator enable when using DM_REGULATOR
by Adam Ford 16 Feb '19

16 Feb '19

When DM_REGULATOR is enabled, the driver attempts to call regulator_autoset() which expects the regulators to be on at boot and/or always on and fails if they are not true. For a more generic approach, this patch just calls regulator_set_enable() which shouldn't have such restrictions.

[U-Boot] [RESEND PATCH 0/3] ARM: liteboard: move towards driver model and device-tree boot
by Marcin Niestroj 16 Feb '19

16 Feb '19

Hi, This patch moves board support code to use driver model where possible and device-tree bot. As part of that we import DTS files from Linux v4.20. One minor patch here is to use random ethaddr in order to make network usable on that board by default. This is a resend of patches [1]. Everything was rebased on master.

[U-Boot] [PATCH] MTD: nand: mxs_nand: Allow driver to auto setup ECC in SPL
by Adam Ford 16 Feb '19

16 Feb '19

The initialization of the NAND in SPL hard-coded ecc.bytes, ecc.size, and ecc.strength which may work for some NAND parts, but it not appropriate for others. With the pending patch "mxs_nand: Fix BCH read timeout error on boards requiring ECC" the driver can auto configure the ECC when these entries are blank.

[U-Boot] [PATCH 1/2] davinci: da850evm: Move BSS to SDRAM because SRAM is full
by Adam Ford 16 Feb '19

16 Feb '19

In order to fully support SPL_OF_CONTROL, we need BSS to be a bit larger. This patch relocates BSS to SDRAM instead of SRAM which is similar to how ARMv7 boards (like OMAP2+) do it. This means two new variables are required: CONFIG_SPL_BSS_START_ADDR set to DAVINCI_DDR_EMIF_DATA_BASE CONFIG_SPL_BSS_MAX_SIZE is set to 0x1080000 which is 1 byte before the location where U-Boot will load.
