[PATCH 02/15] Revert "platform/olpc: Make ec explicitly non-modular"

It doesn't make sense to always have this built-in, e.g. on ARM multiplatform kernels. A better way to address the problem the original commit aimed to solve is to fix Kconfig. This reverts commit f48d1496b8537d75776478c6942dd87f34d7f270. Signed-off-by: Lubomir Rintel --- drivers/platform

[PATCH 0/15] Add support for OLPC XO 1.75 Embedded Controller

Hi. This patchset adds support for the Embedded Controller on an OLPC XO 1.75 machine. OLPC XO 1.75 is a MMP2 based ARM laptop. It plugs into the existing OLPC platform infrastructure, currently used by the x86 based models. The EC operates in SPI master mode, meaning the SOC is the SPI slave. It
