* IXP: Make IXP buildable with arm-linux- toolchainsMarek Vasut2012-03-26-0/+3
| | | | | | | | | | | Add -EB flag to LD to switch endianness of the linker. This should make armeb targets buildable again. Also, make use of U-Boot's internal libgcc instead of toolchain's one, this works around the use of libraries from GCC, which might be little endian.

* armv7: omap3: leave outer cache enabledAneesh V2012-02-27-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Mainline kernel for OMAP3 doesn't enable L2 cache It expects L2$ to be enabled by ROM-code/bootloader. Leaving L2$ enabled can be troublesome in cases where the L2 cache is not under CP15 control, such as in Cortex-A9. This problem is explained in detail in the commit dc7100f4080952798413fb63bb4134b22c57623a However, this problem doesn't apply to Cortex-A8 because L2$ in Cortex-A8 is under CP15 control and hence the generic armv7 maintenance opertions work for it. As such we can make an exception for OMAP3 and leave the L2$ enabled when we jump to kernel. This is done by removing the strongly-linked implementation of v7_outer_cache_disable() and allowing it to fall back to the weakly linked implementation that doesn't do anything.

* dm6467Tevm: Use a common configuration file for davinci_dm6467evm and ↵prabhakar.csengg@gmail.com2012-02-27-1/+1
| | | | | | | | | | | | | | | | | | | | davinci_dm6467Tevm In commit 2d575e46859dd9127a9cec731ace77523e6ea2ab a separate header file was introduced for the DM6467T EVM, include/configs/davinci_dm6467Tevm.h. The substantial difference between the davinci_dm6467evm and the davinci_dm6467Tevm configuration is a single bit in the hardware revision that is passed to the Linux kernel and davinci_dm6467evm has REFCLK_FREQ = 27000000 where as davinci_dm6467Tevm.h has a REFCLK_FREQ = 33000000. This patch removes include/configs/davinci_dm6467Tevm.h. Instead the include/configs/davinci_dm6467evm.h configuration is used for DM6467T EVMs and renamed CFG_REFCLK_FREQ to CONFIG_REFCLK_FREQ and CONFIG_REFCLK_FREQ is defined in boards.cfg.

* mx28: fix SPL code to make USB booting workMatthias Fuchs2012-02-27-1/+20
| | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes booting i.MX28 CPUs via USB download. In this mode the CPU's bootrom implements a USB HID device that accepts a bootstream. When downloading the bootstream via USB, first the SPL code is received and executed. Then the u-boot image is received and called. The USB bootmode is interrupt driven. This patch fixes two things: 1) The ARM's fast interrupt mode is disabled when the SPL code has been run. So save and restore the CPSR register. 2) Save and restore c1 control register: the exception vector location needs to be set back to bootrom space to make the USB interrupts work again. The SPL code needs to change this option for the ram size probing. Signed-off-by: Matthias Fuchs <matthias.fuchs@esd.eu> Acked-by: Marek Vasut <marek.vasut@gmail.com>
