U-Boot provides MALLOC for runtime temporary memory management and
LMB for bootm memory management. There is not a mechanism for permanent
memory management. so that the memory blocks are easy to overlap with
each other.
What does permanent memory mean ?
- The memory can't be touched by U-Boot(ATF/OPTEE/SHM/kernel-reserved, etc);
- The memory occupied even in kernel, such as some firmware load buffer;
This patch introduces sysmem to do permanent memory management, which
implements base on LMB. It provides memory block (pool):
- init;
- add;
- alloc;
- free;
- reserve;
- stat;
- overflow check;
Here is an example for RK3399 sysmem boot stat(assume the "fdt" region is Overflow)
