[Tboot-changelog] changeset in code: Extend low memory range reserved for logs

[Pawel R. <paw...@in...>]

details: http://hg.code.sf.net/p/tboot/code/code?cmd=changeset;node=b06289220ef8
description:
	Extend low memory range reserved for logs

	Some platforms with higher core count had the issue of logs
	overflowing the memory range reserved for them, and thus
	overwriting themselves, leaving just a bit of last lines
	of logs to be later read.

	Before range was 32KB, now it is 200KB which HOPEFULLY
	won't need further extensions

	WARNING:
	This patch causes logs to be unreadable with older versions
	of txt-stat. If you're using TBOOT with this patch, please
	swap your txt-stat for the one built with this patch too.
