When building for a TPL/SPL setup (e.g. on the RK3368), we need the
TPL stage to have the extra space for for the 'Rockchip SPL name'
(i.e. 'RK33' word). Yet, the SPL will start execution at its first
word (i.e. the first word in the SPL binary needs to be a valid
instruction). To make things a bit more involved, CONFIG_SPL_BUILD
is defined both for the SPL and the TPL stage.
To avoid having to explicitly test for the first stage (TPL, if and
only if TPL and SPL are built, SPL otherwise), this commit modifies
the sequence to repeat the 'b reset' (instead of reserving 4 bytes
of undefined space) at the start of the boot0 hook: if overwritten
(and execution starts at the second word), the first instruction is
still a 'b reset'... if not overwritten, we start on a 'b reset' as
well.
This solution wouldn't even require the check whether we are in the
SPL/TPL build (i.e. CONFIG_SPL_BUILD), but we leave this check in for
documentation purposes.

The inline assembly functions in mon.c assume that the caller will
check for the return value in r0 according to regular ARM calling
conventions.
However, this assumption breaks down if the compiler inlines the
functions. The caller is then under no obligation to use r0 for the
result.
To fix this disconnect, we must explicitly move the return value
from the smc/bl call to the variable that the function returns.

On early K2 devices (eg. K2HK) the secure ROM code does not support
loading secure code to firewall protected memory, before decrypting,
authenticating and executing it.
To load the boot monitor on these devices, it is necessary to first
authenticate and run a copy loop from non-secure memory that copies
the boot monitor behind firewall protected memory, before decrypting
and executing it.
On K2G, the secure ROM does not allow secure code executing from
unprotected memory. Further, ROM first copies the signed and encrypted
image into firewall protected memory, then decrypts, authenticates
and executes it.
As a result of this, we cannot use the copy loop for K2G. The
mon_install has to be modified to pass the address the signed and
encrypted secure boot monitor image to the authentication API.
For backward compatibility with other K2 devices and K2G GP,
the mon_install API still supports a single argument. In this case
the second argument is set to 0 by u-boot and is ignored by ROM

This converts the following to Kconfig:
CONFIG_ENV_IS_IN_MMC
CONFIG_ENV_IS_IN_NAND
CONFIG_ENV_IS_IN_UBI
CONFIG_ENV_IS_NOWHERE
In fact this already exists for sunxi as a 'choice' config. However not
all the choices are available in Kconfig yet so we cannot use that. It
would lead to more than one option being set.
In addition, one purpose of this series is to allow the environment to be
stored in more than one place. So the existing choice is converted to a
normal config allowing each option to be set independently.
There are not many opportunities for Kconfig updates to reduce the size of
this patch. This was tested with
./tools/moveconfig.py -i CONFIG_ENV_IS_IN_MMC
And then manual updates. This is because for CHAIN_OF_TRUST boards they
can only have ENV_IS_NOWHERE set, so we enforce that via Kconfig logic
now.

U-Boot has up until now built with -fpic for the MIPS architecture,
producing position independent code which uses indirection through a
global offset table, making relocation fairly straightforward as it
simply involves patching up GOT entries.
Using -fpic does however have some downsides. The biggest of these is
that generated code is bloated in various ways. For example, function
calls are indirected through the GOT & the t9 register:
8f998064 lw t9,-32668(gp)
0320f809 jalr t9
Without -fpic the call is simply:
0f803f01 jal be00fc04 <puts>
This is more compact & faster (due to the lack of the load & the
dependency the jump has on its result). It is also easier to read &
debug because the disassembly shows what function is being called,
rather than just an offset from gp which would then have to be looked up
in the ELF to discover the target function.
Another disadvantage of -fpic is that each function begins with a
sequence to calculate the value of the gp register, for example:
3c1c0004 lui gp,0x4
279c3384 addiu gp,gp,13188
0399e021 addu gp,gp,t9
Without using -fpic this sequence no longer appears at the start of each
function, reducing code size considerably.
This patch switches U-Boot from building with -fpic to building with
-fno-pic, in order to gain the benefits described above. The cost of
this is an extra step during the build process to extract relocation
data from the ELF & write it into a new .rel section in a compact
format, plus the added complexity of dealing with multiple types of
relocation rather than the single type that applied to the GOT. The
benefit is smaller, cleaner, more debuggable code. The relocate_code()
function is reimplemented in C to handle the new relocation scheme,
which also makes it easier to read & debug.
Taking maltael_defconfig as an example the size of u-boot.bin built
using the Codescape MIPS 2016.05-06 toolchain (gcc 4.9.2, binutils
2.24.90) shrinks from 254KiB to 224KiB.

The name is kept generic as it is not at all dependent on
powerpc arch and any other arch could want to also print

In addition, as the Makefile compiles cmd/reginfo.c only when
CONFIG_CMD_REGINFO is set, there is no need to enclose the U_BOOT_CMD

Lets all remove the #ifdefs around the U_BOOT_CMD as this
