Current ARM assembler helper for the 'return to caller' pseudo-instruction
turns 'ret lr' into 'mov pc, lr' for ARMv5TE. This causes the core to remain
in its current ARM state even when the routine doing the 'ret' was called
from Thumb-1 state, triggering an undefined instruction exception.
This causes early run-time failures in all boards compiled using the Thumb-1
instruction set (for instance the Open-RD family).
ARMv5TE supports 'bx lr' which properly implements interworking and thus
correctly returns to Thumb-1 state from ARM state.
This change makes 'ret lr' turn into 'bx lr' for ARMv5TE.

Re-use of routines embedded in the Boot ROM requires a function

For LD11 and LD20 SoCs, the RST_n pin is asserted by default. If
the EXT_CSD[162], bit[1:0] (RST_n_ENABLE) is fused, the eMMC device
would stay in the reset state until its RST_n pin is deasserted by
software.
Currently, this is cared by an ad-hoc way because the eMMC hardware
reset provider is not supported in U-Boot for now. This code should
be re-written once the "mmc-pwrseq-emmc" binding is supported.

For LD20 SoC, the last 64 byte of each DRAM bank is used for the

Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
U-Boot needs to set up available memory area(s) in dram_init() and
dram_init_banksize(). It is platform-dependent how to detect the
memory banks. Currently, UniPhier adopts the memory banks _alleged_
by DT. This is based on the assumption that users bind a correct DT
in their build process.
Come to think of it, the DRAM controller has already been set up
before U-Boot is entered (because U-Boot runs on DRAM). So, the
DRAM controller setup register seems a more reliable source of any
information about DRAM stuff. The DRAM banks are initialized by
preliminary firmware (SPL, ARM Trusted Firmware BL2, or whatever),
so this means the source of the reliability is shifted from Device
Tree to such early-stage firmware. However, if the DRAM controller
is wrongly configured, the system will crash. If your system is
running, the DRAM setup register is very likely to provide the
correct DRAM mapping.
Decode the SG_MEMCONF register to get the available DRAM banks.
The dram_init() and dram_init_banksize() need similar decoding.
It would be nice if dram_init_banksize() could reuse the outcome
of dram_init(), but global variables are unavailable at this stage
because the .bss section is available only after the relocation.
As a result, SG_MEMCONF must be checked twice, but a new helper
uniphier_memconf_decode() will help to avoid code duplication.
