*	x86, olpc: fix endian bug in openfirmware workaround	Harvey Harrison	2008-09-24	1	-3/+3
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Boardrev is always treated as a u32 everywhere else, no reason to byteswap the 0xc2 value. The only use is to print out if it is a prerelease board, the test being: (olpc_platform_info.boardrev & 0xf) < 8 Which is currently always true as be32_to_cpu(0xc2) & 0xf = 0 but I doubt that was the intention here. The consequences of the bug are pretty minor though (incorrect boardrev displayed in dmesg when ofw support not configured) Also annotate the temporary used to read the boardrev in the ofw case. The confusion was noticed by Sparse: arch/x86/kernel/olpc.c:206:32: warning: cast to restricted __be32 Signed-off-by: Harvey Harrison <harvey.harrison@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
*	x86: olpc: add One Laptop Per Child architecture support	Andres Salomon	2008-04-29	1	-0/+260
	This adds support for OLPC XO hardware. Open Firmware on XOs don't contain the VSA, so it is necessary to emulate the PCI BARs in the kernel. This also adds functionality for running EC commands, and a CONFIG_OLPC. A number of OLPC drivers depend upon CONFIG_OLPC. olpc_ec_timeout is a hack to work around Embedded Controller bugs.
