* ARM: dts: keystone-k2hk-evm: Add U-boot specific dtsi fileCooper Jr., Franklin2017-06-121-0/+15
| | | | | | | | | | With Davinci I2C switching to device model, K2HK requires U-boot specific device tree entries. This is only required for I2C 1 which is needed extremely early during the boot process.

| | | | | | | | | commit 06a040a31bcf ("cmd: mtdparts: fix null pointer dereference in parse_mtdparts") removed the initialization of a pointer variable, which is subsequently used in a debug() call.

* board_f: fix calculation of reloc_offLothar Waßmann2017-06-121-2/+5
| | | | | | | | | | | | | | relocate_code() calculates the relocation offset wrt. the symbol __image_copy_start which happens to have the same value as CONFIG_TEXT_BASE on most systems. When creating an i.MX boot image with an integrated IVT it is convenient to have CONFIG_TEXT_BASE point to the start of the IVT that is prepended to the actual code. Thus CONFIG_TEXT_BASE will differ from __image_copy_start, while the calculation 'gd->relocaddr - __image_copy_start' still gives the right relocation offset.

* ARM: remove bogus cp_delay() functionLothar Waßmann2017-06-121-14/+1
| | | | | | | | | | | The cp_delay() function was introduced because of a missing 'volatile' attribute to the 'asm' statement in get_cr() which led to the 'mrc' instruction in get_cr() being optimised out eventually. This has been fixed in commit 53fd4b8c22bb ("arm: mmu: Add missing volatile for reading SCTLR register") but the bogus cp_delay() function which was introduced as a workaround for the malfunctioning get_cr() was never removed.

* ARM: fixed relocation using proper alignmentManfred Schlaegl2017-06-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | Using u-boot-2017.05 on i.MX6UL we ran into following problem: Initially U-Boot could be started normally. If we added one random command in configuration, the newly generated image hung at startup (last output was DRAM: 256 MiB). We tracked this down to a data abort within relocation (relocated_code). relocated_code in arch/arm/lib/relocate.S copies 8 bytes per loop iteration until the source pointer is equal to __image_copy_end. In a good case __image_copy_end was aligned to 8 bytes, so the loop stopped as suggested, but in an errornous case __image_copy_end was not aligned to 8 bytes, so the loop ran out of bounds and caused a data abort exception. This patches solves the issue by aligning __image_copy_end to 8 byte using the linker script related to arm. I don't know if it's the correct way to solve this, so some review would be very appreciated.

| * cmd/fdt: support single value replacement within an arrayHannes Schmelzer2017-06-091-8/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With this commit we can modify single values within an array of a dts property. This is useful if we have for example a pwm-backlight where we want to modifiy the pwm frequency per u-boot script. The pwm is described in dts like this: backlight { pwms = <0x0000002b 0x00000000 0x004c4b40>; }; For changing the frequency, here the 3rd parameter, we simply type: fdt set /backlight pwms <? ? 0x1E8480>; For doing all this we: - backup the property content into our 'SCRATCHPAD' - only modify the array-cell if the new content doesn't start with '?'
