[U-Boot] [PATCH v2 1/2] libfdt: Correct fdt handling of overlays without fixups and base trees without symbols
by Stefan Agner 14 Jan '17

14 Jan '17

From: David Gibson <david(a)gibson.dropbear.id.au> The fdt_overlay_apply() function purports to support the edge cases where an overlay has no fixups to be applied, or a base tree which has no symbols (the latter can only work if the former is also true). However it gets it wrong in a couple of small ways: * In the no fixups case, it doesn't fail immediately, but will attempt fdt_for_each_property_offset() giving -FDT_ERR_NOTFOUND as the node offset, which will fail. Instead it should succeed immediately, since there's nothing to do. * In the case of no symbols, it again doesn't fail immediately. However if there is an actual fixup it will fail with an unexpected error, because -FDT_ERR_NOTFOUND is passed to fdt_getprop() when attempting to look up the symbols. We should instead return -FDT_ERR_NOTFOUND directly. Both of these errors lead to the code returning misleading error codes in failing cases.

[U-Boot] [PATCH V2 0/7] dm: universal_c210: support the DM_PMIC
by Jaehoon Chung 14 Jan '17

14 Jan '17

This patchset is for supporting pmic driver-mode on universal_c210 board. It's using i2c-s3c24x0.c file. (Fixes some complier error issue.) Remove the soft_i2c codes in universal.c.

Re: [U-Boot] Rockchip RK3288 regulator device table problem
by Rick Bronson 14 Jan '17

14 Jan '17

Hi Simon, I'm not sure what to do about (in drivers/power/regulator/rk808.c): static const struct rk808_reg_info rk808_ldo[] = { { 1000000, 100000, LDO1_ON_VSEL, 5, }, ... I had to change this table as my LDO values are different for this board. I'd like to fix it to take values from the device tree but couldn't find an example. Maybe you can point me to one. Thanks, Rick

[U-Boot] [PATCH] defconfig: Add a config for AM335x High Security EVM
by Andrew F. Davis 14 Jan '17

14 Jan '17

Add a new defconfig file for the AM335x High Security EVM. This config is specific for the case of memory device booting. Memory device booting is handled separatly from peripheral booting on HS devices as the load address changes. This defconfig is the same as for the non-secure part, except for: CONFIG_TI_SECURE_DEVICE option set to 'y' CONFIG_ISW_ENTRY_ADDR updated for secure images. CONFIG_FIT_IMAGE_POST_PROCESS option set to 'y' CONFIG_SPL_FIT_IMAGE_POST_PROCESS option set to 'y' CONFIG_USE_TINY_PRINTF option set to 'y' to reduce SPL size CONFIG_SPL_SYS_MALLOC_SIMPLE set to 'y' to reduce SPL size Signed-off-by: Andrew F.
