sandbox, test: add test for GPIO_HOG function

2020-07-05T12:06:09+00:00

currently gpio hog function is not tested with "ut dm gpio"
so add some basic tests for gpio hog functionality.

For this enable GPIO_HOG in sandbox_defconfig, add
in DTS some gpio hog entries, and add testcase in
"ut dm gpio" command.

riscv: use log functions in fdt_fixup

2020-07-03T07:09:12+00:00

Replace printf() and debug() by log_err() and log_debug().

"No reserved memory region found in source FDT\n" is not an error but a
debug information.

%s/can not/cannot/ - use the more common spelling.

riscv: Use optimized version of fdtdec_get_addr_size_no_parent

2020-07-03T07:09:00+00:00

fdtdec_get_addr_size_no_parent is not an optimized version if parent
node is already available with the caller.

Use fdtdec_get_addr_size_auto_parent to read the "reg" property

Not all errors are fatal. If a reserved memory node already exists in the
destination device tree, we can continue to boot without failing.

riscv: Enable CONFIG_OF_BOARD_FIXUP by default for OF_SEPARATE

2020-07-02T02:03:09+00:00

Starting from OpenSBI v0.7, the SBI firmware inserts/fixes up the
reserved memory node for PMP protected memory regions. All RISC-V
boards need to copy the reserved memory node from the device tree
provided by the firmware to the device tree used by U-Boot.

Turn on CONFIG_OF_BOARD_FIXUP by default for OF_SEPARATE.

The copy of reserved memory node from source dtb to destination dtb
can be avoided if they point to the same place. This is useful when
