Subject: [PATCH] powerpc/ptdump: Fix display a BAT's size unit
Date: Fri, 26 Nov 2021 11:30:03 +0100	[thread overview]
Message-ID: <f16c30f5c9185a63335322cf1a8b22f189d335ef.1637922595.git.christophe.leroy@csgroup.eu> (raw)

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.
