HREF V1 updates
This patch is part of WP254081 which depends on WP252006. * Fixed I2C, use real timeouts instead of counter * Undefined CONFIG_BOOTTIME, since it as to be changed to new timer.c * Merged V1 patches from Bangalore The patches were merged manually, because of the differences of the U-Boot baseline (Bangalore U-Boot 1.3.1, Lund 2009.11). The original patches were created by Rabin Vincent <rabin.vincent@stericsson.com>. and were applied originally to Branches: blr_lsp, remotes/origin/blr_lsp Follows: qpppaaa_20100210_094651 0001-u8500-gpio-add-I2C0-altfun.patch 0002-u8500-use-correct-v1-macros.patch 0003-emmc-clean-up-paritioning.patch 0004-u8500-remove-incorrect-ram-settings.patch 0005-u8500-gpio-remove-unnecessary-ifdefs.patch 0006-u8500-add-ED-v1-detection-and-handle-eMMC-diff.patch 0008-u8500-mmc-don-t-disable-altfuns.patch 0009-u8500-gpio-remove-unused-defined.patch 0010-u8500-mmc-add-barrier-for-while-loop.patch 0011-u8500-mmc-handle-non-block-addressed-cards.patch 0012-u8500-mmc-remove-unused-gpio-settings-on-v1.patch 0013-u8500-emmc-build-fix.patch 0014-u8500-handle-v1-gpios-and-clocks.patch 0015-mmc-build-fix-for-block-addressing.patch 0016-u8500-add-clocks-and-hardware-files.patch 0017-u8500-enable-PRCUM-timers-reg-for-ED.patch 0018-u8500-handle-MTU-for-v1-ED.patch 0019-u8500-emmc-remove-unnecessary-GPIO-settings.patch 0020-u8500-remove-dead-code.patch 0021-u8500-add-working-MTU-timer.patch 0022-pl011-empty-rx-fifo-if-necessary.patch 0023-u8500-gpio-fix-cont-handling-in-altfunc.patch 0024-u8500-reduce-bootdelay-to-1-and-enable-zero-check.patch 0025-u8500-disable-forcing-of-verify-but-set-n-by-default.patch 0029-u8500-fix-some-gpio-settings.patch 0030-emmc-make-v1-paritioning-differences-explicit.patch Signed-off-by: Michael Brandt <Michael.Brandt@stericsson.com> Change-Id: I1106702e393c34f630e71f071e06c3952b0d3a1a Reviewed-on: http://gerrit.lud.stericsson.com/gerrit/182 Reviewed-by: Michael BRANDT <michael.brandt@stericsson.com> Tested-by: Jonas ABERG <jonas.aberg@stericsson.com> Reviewed-by: Jonas ABERG <jonas.aberg@stericsson.com>
