xtensa: drop unused sections and remapped reset handlers

2015-11-03T14:19:39+00:00

There are no .bootstrap or .ResetVector.text sections linked to the
vmlinux image, drop these sections from vmlinux.ld.S. Drop
RESET_VECTOR_VADDR definition only used for .ResetVector.text.

Drop remapped copies of primary and secondary reset vectors, as modern
gdb don't have problems stepping through instructions at arbitrary
locations. Drop corresponding sections from the corresponding linker
scripts.

xtensa: enable building of all dtbs

2015-10-27T21:12:16+00:00

Enable building all dtb files when CONFIG_OF_ALL_DTBS is enabled. The dtbs
are not really dependent on a platform being enabled or any other kernel
config, so for testing coverage it is convenient to build all of the dtbs.
This builds all dts files in the tree, not just targets listed.

xtensa: nommu: fix Image.elf reset code and ld script

2014-10-21T09:28:52+00:00

Don't hardcode kernel entry address as 0x3000 or 0xd0003000, use
LOAD_MEMORY_ADDRESS macro. Don't compile MMU remapping code and don't try
to link it when building noMMU configuration.

xtensa: configure kc705 for highmem

2014-08-14T07:59:25+00:00

Enable all memory available on KC705 (1G - 128M) by default. Update memory
node in DTS and also limit usable memory in bootargs in case memmap is
passed from the bootloader.
