From: Jason Liu <jason.hui(a)linaro.org> Add the initial support for Freescale i.MX6Q Sabre Lite board Signed-off-by: Dirk Behme <dirk.behme(a)de.bosch.com> Signed-off-by: Jason Liu <jason.hui(a)linaro.org> CC: Eric Nelson <eric.nelson(a)boundarydevices.com> --- V4: Rebase board_mmc_getcd() against http://patchwork.ozlabs.org/patch/132398/ This does mean that this patch needs that patch to be applied. V3: Add a readme. Enable the usboh3 clock: Bits 0 and 1 of CCM_CCGR7 are the usboh3 clock enable bits. Enabling this clock is necessary for the USB download: -DATA 4 0x020c4080 0x000003FC +DATA 4 0x020c4080 0x000003FF V2: change the default script to let linaro image boot, and also change the default env to dev 0, which is normal SD slot, not the Micro-SD slot MAINTAINERS | 1 board/freescale/mx6qsabrelite/Makefile | 42 ++++++ board/freescale/mx6qsabrelite/imximage.cfg | 170 ++++++++++++++++++++++++++ board/freescale/mx6qsabrelite/mx6qsabrelite.c | 151 +++++++++++++++++++++++ boards.cfg | 1 doc/README.mx6qsabrelite | 67 ++++++++++ include/configs/mx6qsabrelite.h | 162 ++++++++++++++++++++++++ 7 files changed, 594 insertions(+) create mode 100644 board/freescale/mx6qsabrelite/Makefile create mode 100644 board/freescale/mx6qsabrelite/imximage.cfg create mode 100644 board/freescale/mx6qsabrelite/mx6qsabrelite.c create mode 100644 include/configs/mx6qsabrelite.h Index: freescale-u-boot-imx.git/MAINTAINERS =================================================================== --- freescale-u-boot-imx.git.orig/MAINTAINERS +++ freescale-u-boot-imx.git/MAINTAINERS @@ -579,6 +579,7 @@ Jason Liu <r64343(a)freescale.com> mx53evk i.MX53 mx53loco i.MX53 mx6qarm2 i.MX6Q + mx6qsabrelite i.MX6Q Enric Balletbo i Serra <eballetbo(a)iseebcn.com> Index: freescale-u-boot-imx.git/board/freescale/mx6qsabrelite/Makefile =================================================================== --- /dev/null +++ freescale-u-boot-imx.git/board/freescale/mx6qsabrelite/Makefile @@ -0,0 +1,42 @@ +# +# Copyright (C) 2007, Guennadi Liakhovetski <lg(a)denx.de> +# +# (C) Copyright 2011 Freescale Semiconductor, Inc. +# +# This program is free software; you can redistribute it and/or +# modify it under the terms of the GNU General Public License as +# published by the Free Software Foundation; either version 2 of +# the License, or (at your option) any later version. +# +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

[U-Boot] [PATCH] mx28: fix clearing of IRQs in power init
by Zach Sadecki 11 Jan '12

11 Jan '12

There are 2 locations in the power init code for the mx28 where IRQs are not being cleared because incorrect methods to clear those bits were being used. This was causing my board to get stuck waiting for POWER_CTRL_VDD5V_DROOP_IRQ to clear. Using the correct method to clear the IRQs fixes it.

[U-Boot] [PATCH 1/5 v2] mtd/nand: Add function board_nand_init_tail() for some special NAND controllers
by Shengzhou Liu 11 Jan '12

11 Jan '12

In some NAND controllers there is a size limitation of RAM buffer(2K bytes). To support large-page NAND chips with greater than 2K pagesize, we need a large buffer, but we don't know pagesize before calling nand_scan_ident(), for more flexible and to identify different cases of large-page greater than 2K bytes, we have a board_nand_init_tail() between nand_scan_ident() and nand_scan_tail().
