From 0adcbaf78f6267baf4eecc201107d8f8ff3b200c Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Mon, 11 Feb 2013 14:46:00 -0800 Subject: [PATCH 1/8] ARM: OMAP1: Fix build related to kgdb.h no longer including serial_8250.h MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Commit 16559ae4 (kgdb: remove #include from kgdb.h) had a side effect of breaking omap1_defconfig build as some headers were included indirectly: arch/arm/mach-omap1/board-h2.c:249: error: ‘INT_KEYBOARD’ undeclared here (not in a function) ... This worked earlier as linux/serial_8250.h included linux/serial_core.h, via linux/serial_8250.h from linux/kgdb.h. Fix this by including the necessary headers directly.

The chip-selects should have been unreserved at the end of the probe function, but the code to unreserve them appears to have ended up in the gpmc_calc_timings() function and hence, this is causing problems requesting chip-selects. Fix this merge error by unreserving the chip-selects at the end of the probe, but before we call the gpmc child probe functions (for device-tree) which request a chip-select.
