efi: Correct smbios-table installation
At present this code allocates memory when writing the tables and
then unnecessarily adds another memory map when installing it.
Adjust the code to allocate the tables using the normal U-Boot
mechanism. This avoids doing an EFI memory allocation early in
U-Boot, which may use memory that would be overwritten by a
'load' command, for example.

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.
Add two new 'nomap' functions which clearly make this exeption to how
sandbox works.
This should allow EFI apps to access ACPI tables with sandbox, e.g. for
testing purposes.

fw_env: keep calling read() until whole flash block is read
It's totally valid for read() to provide less bytes than requested
maximum. It may happen if there is no more data available yet or source
pushes data in small chunks.
This actually happens when trying to read env data from NVMEM device.
Kernel may provide NVMEM content in page size parts (like 4096 B).
This fixes warnings like:
Warning on /sys/bus/nvmem/devices/u-boot-env0/nvmem: Attempted to read 16384 bytes but got 4096

fw_env: fix reading NVMEM device's "compatible" value
Call to fread() was changed to check for return value. The problem is it
can't be checked for returning 1 (as it is) to determine success.
We call fread() with buffer size as "size" argument. Reading any
"compatible" value shorter than buffer size will result in returning 0
even on success.
Modify code to use fstat() to determine expected read length.
This fixes regression that broke using fw_env with NVMEM devices.
Unlike all other supported Tegra devices and most known Tegra devices, the
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
faulty, the device will hang in a permanent brick state. Exiting from this
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
state and triggers RCM if it is pressed.
