Add 'fdt rsvmem' test which works as follows: - Create custom FDT with single reserved memory (rsvmem) entry, map it to sysmem - Add new rsvmem entry - Delete existing older rsvmem entry - Add new rsvmem entry again - Always print the rsvmem list and validate it
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.
