acpi: Write pointers to tables instead of addresses
Sandbox uses an API to map between addresses and pointers. This allows
it to have (emulated) memory at zero and avoid arch-specific addressing
details. It also allows memory-mapped peripherals to work.
As an example, on many machines sandbox maps address 100 to pointer
value 10000000.
However this is not correct for ACPI, if sandbox starts another program
(e.g EFI app) and passes it the tables. That app has no knowledge of
sandbox's address mapping. So to make this work we want to store 10000000 as the value in the table.

sandbox works.

HTC One X has no hardware way to enter APX/RCM mode, which may lead to a
dangerous situation when, if BCT is set correctly and the bootloader is

state can be done only by disassembling the device and shortening the
testpad to the ground.
To prevent this or to minimize the probability of such an accident, it was
proposed to add the RCM rebooting hook as early into SPL as possible since
SPL is much more robust and has minimal changes that can break bootflow.
gpio_early_init_uart() function was chosen as it is the earliest function
exposed for setup by the device. Hook performs a check for volume up button
