Add 'fdt get addr' test which works as follows:
- Create fuller FDT, map it to sysmem
- Get address of various properties
- Compare addresses calculated by UT and fdt command
This test is special in that it has to go through gruesome remapping scheme
where the test calculates:
- pointer offsets of the generated FDT root and the property being tested
- map_sysmem() result of environment variable "fdtaddr" and the one set
by the test matching address of property being tested
- difference between the later and the former, to obtain offset of the
DT property from start of DT
The offsets must match in both the UT and the tested U-Boot, if they do
not, the test fails.
The test case can be triggered using:
"
./u-boot -Dc 'ut fdt'
"
To dump the full output from commands used during test, add '-v' flag.
