1. Convert all linker symbols to char[] type so that we can get the
corresponding address by calling array name 'var' or its address
'&var'. In this way, we can avoid some potential issues[1].
2. Remove unused symbol '_TEXT_BASE'. It has been abandoned and has
not been referenced by any source code.
3. Move '__data_end' to the arch x86's own sections header as it's
only used by x86 arch.
4. Remove some duplicate declared linker symbols. Now we use the
standard header file to declare them.
[1] This patch fixes the boot failure on MIPS target. Error log:
SPL: Image overlaps SPL

How to use U-Boot on MX6Q/DL Udoo boards ---------------------------------------- - Build U-Boot for MX6Q/DL Udoo boards: $ make mrproper $ make udoo_defconfig $ make This will generate the SPL image called SPL and the u-boot.img. - Flash the SPL image into the SD card: sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync - Flash the u-boot.img image into the SD card: sudo dd if=u-boot.img of=/dev/mmcblk0 bs=1k seek=69; sync - Insert the SD card in the board, power it up and U-Boot messages should come up.
