Introduce generic link section.h symbol files We create a separate header file for link symbols defined by the link scripts. It is helpful to have these all in one place and try to make them common across architectures. Since Linux already has a similar file, we bring this in even though many of the symbols there are not relevant to us. Each architecture has its own asm/sections.h where symbols specifc to that architecture can be added. For now everything except AVR32 just includes the generic header. One change is needed in arch/avr32/lib/board.c to make this conversion work. Reviewed-by: Tom Rini <trini@ti.com> (version 5) Signed-off-by: Simon Glass <sjg@chromium.org>

dm: spl: Support device tree when BSS is in a different section At present in SPL we place the device tree immediately after BSS. This avoids needing to copy it out of the way before BSS can be used. However on some boards BSS is not placed with the image - e.g. it can be in RAM if available. Add an option to tell U-Boot that the device tree should be placed at the end of the image binary (_image_binary_end) instead of at the end of BSS. Note: A common reason to place BSS in RAM is to support the FAT filesystem. We should update the code so that it does not use so much BSS.
