- Remove a few useless -D<flag>
- Always use '?=' as opposed to ':=' for consistent behavior with
'CFG_FOO=y make' and 'make CFG_FOO=y'
=> Use this form when both enabled and disabled are valid options
- Add macro: $(call force,CFG_FOO,y) to set a variable and make
sure it does not conflict with external values that may be given
on the command line or in the environment
=> Use this form when the variable can only have the specified value
(any other value would be invalid). 'override CFG_FOO := y' would
be correct, too, but would not detect conflicting values.
- Always include mk/conf.mk last so that the platform definitions
always take precedence over the global configuration

arm: imx: add i.MX 6UltraLite and EVK board support

The i.MX 6UltraLite[1] is a high performance, ultra-efficient processor
family featuring an advanced implementation of a single ARM® Cortex®-A7
core.

This patch add i.MX 6Ulralite EVK board support:
1. Add a uart driver for i.MX platforms
2. Introduce plat-imx for i.MX platforms
3. Introduce i.MX6 UltraLite platform
4. This patch has been tested using the following step,
4.1. build step:
PLATFORM_FLAVOR=mx6ulevk make ARCH=arm PLATFORM=imx
${CROSS_COMPILE}-objcopy -O binary out/arm-plat-imx/core/tee.elf optee.bin
copy optee.bin to the first partition of SD card which is used for boot.
4.2. Boot setting in uboot:
run loadfdt;
run loadimage;
fatload mmc 1:1 0x9c100000 optee.bin;
run mmcargs;
bootz ${loadaddr} - ${fdt_addr};
5. pass xtest

Note:
CAAM is not implemented now, this will be added later.

arm/pager: move init temp storage of hashes

When a paged OP-TEE binary is copied into secure memory with unpaged
code and data in the correct location, but with init code and hashes of
paged pages starting at the start of the .bss section. If .bss is large
enough init code and hashes will fit entirely in the .bss section and as
long as .bss is unused the data there is safe.

This assumption will not be true any longer if .bss shrinks dramatically
due to reduced size of mpa scratch memory.

With this patch the hashes will be copied to a temporary safe location
right after the init code. This location is the same as the start of the
.text_pageable section so the hashes must be copied to the final
location before the pager is initialized.
