I need to mapped all (reduce size of highmem) the memory with kernel. but my default boot log is as below.
"Memory: 1222984K/1446656K available (10240K kernel code, 2287K rwdata, 3232K rodata, 2048K init, 497K bss, 190904K reserved, 32768K cma-reserved, 805632K highmem)"
How/where highmem value is define ?
What is default value ?
Total DRAM : 2GB
