powerpc/ppc64: Clean up the boot-time settings display
At boot we display a bunch of low level settings which can be useful to
know, and can help to spot bugs when things are fundamentally
misconfigured.
At the moment they are very widely spaced, so that we can accommodate
the line:
ppc64_caches.dcache_line_size = 0xYY
But we only print that line when the cache line size is not 128, ie.
almost never, so it just makes the display look odd usually.
The ppc64_caches prefix is redundant so remove it, which means we can
align things a bit closer for the common case. While we're there
replace the last use of camelCase (physicalMemorySize), and use
phys_mem_size.
Before:
Starting Linux PPC64 #104 SMP Wed Aug 6 18:41:34 EST 2014
-----------------------------------------------------
ppc64_pft_size = 0x1a
physicalMemorySize = 0x200000000
ppc64_caches.dcache_line_size = 0xf0
ppc64_caches.icache_line_size = 0xf0
htab_address = 0xdeadbeef
htab_hash_mask = 0x7ffff
physical_start = 0xf000bar
-----------------------------------------------------
After:
Starting Linux PPC64 #103 SMP Wed Aug 6 18:38:04 EST 2014
-----------------------------------------------------
ppc64_pft_size = 0x1a
phys_mem_size = 0x200000000
dcache_line_size = 0xf0
icache_line_size = 0xf0
htab_address = 0xdeadbeef
htab_hash_mask = 0x7ffff
physical_start = 0xf000bar
-----------------------------------------------------
This patch is final, no bike shedding ;)
