android_image_parse_kernel_comp() doesn't return valid os
compressed type after android_image_set_kload(), so we add
the env "os_comp" to record compressed type.

If there is not "kernel_addr_c", using "kernel_addr_r" for Image/zImage
on 32-bit platform.
If there is not "kernel_addr_c", adjust load address to promise compressed
kernel can normal boot on 64-bit platform.

- add amp uclass;
- add a simple rockchip amp driver.
An example for amps dts node configure:
amps {
compatible = "uboot,rockchip-amp";
status = "okay";
amp@0 {
description = "mcu-os1";
partition = "mcu1";
cpu = <0x1>; // this is mpidr!
load = <0x800000>;
entry = <0x800000>;
memory = <0x800000 0x400000>;
};
amp@1 {
......
};
......
};
U-Boot loads "mcu-os1" firmware to "0x800000" address from partiton
"mcu1" for cpu[1], the cpu[1] entry address is 0x800000. And
U-Boot reserve memory from 0x800000 with 0x400000 size in order
to make it invisible for kernel.
Please use rockchip tool "mkkrnlimg" to pack firmware binary, example:
./scripts/mkkrnlimg mcu-os1.bin mcu-os1.img

During board_f sequence, it's able to add any count of dram banks
and validate memory layout after reserve_xxx() done, stop bootflow
if there is something wrong.
During board_r sequence, it's able to manage all memory blocks and
add reserve memory blocks for bi_dram[] at late bootflow, it's
nesscessary for AMP boot.

Some platform provides more than one dram banks and reserved firmware
regions (eg. ATF, OP-TEE, etc) by pre-loader dynamically. It means
there are memory holes in board dram layout. What's more, U-Boot will
reserved regions at the late bootflow(eg. firmware reserved for AMP).
So we introduce bidram mechanism to manage GD board bi_dram[], which
provides a way to easily manage memory holes and update bi_dram[]. It
dpends on LMB which provides a good algorithm to manage memory blocks.
What's different from sysmem?
- bidram manage and pass the avaliable memory blocks to kernel;
- sysmem is only for U-Boot memory management to avoid ram overlap,
it doesn't matter about kernel avaliable memory.
