We have wrong units on BAT's sizes (G instead of M, M instead of ...)
---[ Instruction Block Address Translation ]---
0: 0xc0000000-0xc03fffff 0x00000000 4G Kernel x m
1: 0xc0400000-0xc05fffff 0x00400000 2G Kernel x m
2: 0xc0600000-0xc06fffff 0x00600000 1G Kernel x m
3: 0xc0700000-0xc077ffff 0x00700000 512M Kernel x m
4: 0xc0780000-0xc079ffff 0x00780000 128M Kernel x m
5: 0xc07a0000-0xc07bffff 0x007a0000 128M Kernel x m
6: -
7: -
This is because pt_dump_size() expects a size in Kbytes but
bat_show_603() gives the size in bytes.
To avoid risk of confusion, change pt_dump_size() to take bytes.
