MISRA C requires that unsigned constants should have the 'U' suffix, while this
C syntax is not accepted by binutils assembler per binutil manual.
This patch explicitly spells out the unsigned constants used in the assembly
files while tracking the original expressions in comments. This fixes build
failure when using binutils <= 2.26.
v2 -> v3:
* Explicitly spell out the unsigned constants in assembly, instead of
duplicating the macros in headers which break the integrity of the
definitions.
v1 -> v2:
* Define different macros instead of wrapping all unsigned constants.

The previous logic assumes LIBDIR to be /usr/lib64 if it exists.
some x86_64 distros, like ubuntu and debian, the default x86_64 libs(gnu-efi)
are installed into /usr/lib while /usr/lib64 is for i386
~/workspace$ dpkg -L gnu-efi | grep elf_x86_64_efi.lds
/usr/lib/elf_x86_64_efi.lds
~/workspace$ dpkg -S /usr/lib64
libc6-amd64:i386: /usr/lib64
so it failed to compile efi perviously as following errors:

In the hypervisor, physical cpu id is defined as "int" or "uint32_t"
type in the hypervisor. So there are some sign conversion issues
about physical cpu id (pcpu_id) reported by static analysis tool.
Sign conversion violates the rules of MISRA C:2012.
In this patch, define physical cpu id as "uint16_t" type for all
modules in the hypervisor and change related codes. The valid
range of pcpu_id is 0~65534, INVALID_PCPU_ID is defined to the
invalid pcpu_id for error detection, BROADCAST_PCPU_ID is
broadcast pcpu_id used to notify all valid pcpu.
The type of pcpu_id in the struct vcpu and vcpu_id is "int" type,
this will be fixed in another patch.
V1-->V2:
* Change the type of pcpu_id from uint32_t to uint16_t;
* Define INVALID_PCPU_ID for error detection;
* Define BROADCAST_PCPU_ID to notify all valid pcpu.
V2-->V3:
* Update comments for INVALID_PCPU_ID and BROADCAST_PCPU_ID;
* Update addtional pcpu_id;
* Convert hexadecimals to unsigned to meet the type of pcpu_id;
* Clean up for MIN_PCPU_ID and MAX_PCPU_ID, they will be
defined by configuration.
Note: fix bug in the init_lapic(), the pcpu_id shall be less than 8,
this is constraint by implement in the init_lapic().

Per MISRA C, operands to bit-wise operations should have unsigned
types. However, C99 prioritizes to use signed integers for hexadecimal constants
without the 'U' suffixes, leading to tons of bit operations on signed integers.
This patch series add the 'U' suffixes to the constants which are used in bit
operations, and add the intended width of these integers when applicable
(i.e. the target value is at least 32-bit wide) to avoid functional differences
due to signed vs. unsigned extensions. The rule of thumb is:
'0' for signed char/short/int
'0U' for unsigned char/short/int
'0L' for signed long (should be 64-bit)
'0UL' for unsigned long (should be 64-bit)

This patch introduces a configuration symbol RELEASE for managing debug/release
build in a similar way to how we manage PLATFORM.
Note:
1. 'make defconfig RELEASE=1' will still use the CONFIG_RELEASE defined in the
default configuration. The 'RELEASE=1' option has no effect in this case.
2. 'make RELEASE=1' is backward-compatible and enforces a release version to be
built.
v1 -> v2:
* Pass RELEASE instead of CONFIG_RELEASE to silentoldconfig.py to avoid
unintended overriding of the value.

Since .config has PLATFORM now, it is expected that the PLATFORM= command line
option is no longer necessary as long as a proper .config exists.
This patch implements this expectation. Now the platform to be selected is
determined by the following steps.
1. If PLATFORM= is provided on the command line, the specified value is
used.
2. If there is no PLATFORM= on the command line and PLATFORM is defined in
config.mk, its value is used.
3. If neither PLATFORM= on the command line nor config.mk is available, a
predefined default value is used.
v1 -> v2:
* 'make oldconfig' should not pass CONFIG_xxx to the script since config.mk
can be out-dated.
* Change the default value of PLATFORM to SBL for backward compatibility of
'make all'.
