- It provides a way to promise kernel dtb can be loaded successfully
even when the image is damaged.
- This makes developers easily to add what they what just like a "U-Boot" dtb.
- The kern.dtb file is pack into the end of u-boot.bin while ./dts/kern.dtb
is exist.

The 0x0 address is usually allocated by 32-bit uncompressed kernel
and this alloc action is just a peek. Due to LMB core doesn't support
alloc at 0x0 address, we have to alloc the memblk backword a few bytes.
This patch is mainly to avoid fail message from sysmem/LMB.

- Allow request region alloc within the first invisiable region reserved by
bidram when request region has flags M_ATTR_IGNORE_INVISIBLE. This is a
workaround for some firmware memory layout, eg: on RK3308-AArch32, the ATF
region is 0~1M(same as RK3308-AArch64), but the kernel would like to alloc
at 0x00058000.
- Always make kernel reserved-memory alloc successfully and check overlap
with invisible and sysmem allocated regions in sysmem_overflow_check()
before bootm. This makes alloc policy more easier.

1.dev_desc->if_type == IF_TYPE_MMC for SD and eMMC device,
dev_desc->devnum == 1 is SD devices,
dev_desc->devnum == 0 is eMMC devices
2.SD devices do not have rpmb
3.we prefer to use rpmb for eMMC devices, use security
partition for nand or SD devices

Using malloc buffer to load image makes CONFIG_SYS_MALLOC_LEN must be

Because avb android image usually needs a large memory buffer,
always alloc avb android memblk right after U-Boot stack is a
better choice to avoid memblk overlap with others.
Since we have overflow protect magic for U-Boot stack, so we add
a pad(4KB) between them.

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.
