70656c79f3 Exynos5: Add support for USB download boot mode
Exynos5250 supports secondary USB device boot mode. If the iROM fails
to download u-boot from the primary boot device (such as SD or eMMC),
it will try to retrieve from the secondary boot device (such as USB).

a4d40b856f Exynos5: clock: Fix a typo bug in exynos clock init
We intended to clear the bits of CLK_SRC_TOP2 register, instead we were
writing on the reserved bits of src_core1 register. Since the default
value of clk_src_top2 register were itself zero, this typo was not
creating any big issue. But it is better to fix this error for better
readability of the code.

Since we have DT support in exynos_fb and exynos_dp drivers now,

3929fb0a14 Replace __bss_end__ with __bss_end
Note this is a tree-wide change affecting multiple architectures.

At present we use __bss_start, but mostly __bss_end__. This seems
inconsistent and in a number of places __bss_end is used instead.

Change to use __bss_end for the BSS end symbol throughout U-Boot. This
makes it possible to use the asm-generic/sections.h file on all
archs.

ef123c5253 Refactor linker-generated arrays
Refactor linker-generated array code so that symbols
which were previously linker-generated are now compiler-
generated. This causes relocation records of type
R_ARM_ABS32 to become R_ARM_RELATIVE, which makes
code which uses LGA able to run before relocation as
well as after.

Note: this affects more than ARM targets, as linker-
lists span possibly all target architectures, notably
PowerPC.
