* MIPS: bootm: add support for generic relocation of init ramdisksDaniel Schwierzeck2013-08-13-2/+7
| | | | | | | | All linux kernels after v2.6 require a page-aligned location of an external init ramdisk. Enable CONFIG_SYS_BOOT_RAMDISK_HIGH to support this with the generic U-Boot relocation code. Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>

| * fpga: zynqpl: Clear loopback mode during device initSoren Brinkmann2013-08-12-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some versions of the Zynq first stage boot loader enable PCAP loopback during boot regardless of whether or not the boot image includes PL configuration. This behavior only appears in certain boot modes (notably QSPI boot). Attempting to configure the PL with the loopback bit set will result in timeouts and will prevent successful configuration. In order to avoid this problem, and to avoid dependency on the version of the FSBL used to boot the system, ensure that the loopback enable bit is cleared when loading the driver.

| * i2c: soft: Fix typo in CONFIG_SYS_I2C_SOFT_SPEEDMarek Vasut2013-08-03-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In case only the CONFIG_SYS_I2C_SPEED is set in configuration file, the CONFIG_SYS_I2C_SOFT_SPEED is defined as CONFIG_SYS_I2C_SPEED. The CONFIG_SYS_I2C_SOFT_SPEED is then used throughout the driver. Unfortunatelly, due to a typo in the driver, instead of defining CONFIG_SYS_I2C_SOFT_SPEED, an CONFIG_SYS_SOFT_I2C_SPEED was defined and therefore the driver failed to compile. The same applies for CONFIG_SYS_I2C_SOFT_SLAVE , where the swap happens as well. This patch fixes the issue. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Heiko Schocher <hs@denx.de>
* | dts/Makefile: pass -undef -D__DTS__ to cppStephen Warren2013-08-02-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | This brings U-Boot's cpp invocation into line with the way the Linux kernel invokes cpp on device trees. Consistency will be useful to ensure *.dts is portable between the two. -undef also has the added advantage of not defining "linux", so DT property names such as "linux,keymap" don't get mangled.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | *.dts may use #include (via cpp) or /include/ (via dtc; assuming a newer dtc). The choice is up to the creator of the DT. Create a common variable DTC_INCDIRS that lists the paths searched by include statements, and update cpp and dtc invocation to use them. For cpp, also specify -nostdinc to ensure the same set of paths is available to both type of include statement. For dtc, create a new DTC_FLAGS variable to hold all the flags passed to dtc.

* | dts/Makefile: simplify dtc invocationStephen Warren2013-08-02-7/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The invocation of dtc is significantly more complex that it could be, in order to work around an issue on old versions of dtc, which print a message to stdout every time they run. Remove this workaround, on the assumption that people have or will upgrade to a newer version of dtc. This simplifies the build rule significantly. Related, split the invocation of cpp and dtc into separate commands rather than a pipeline, so that if either fail, it is detected. This has the nice benefit of saving off the result of the pre-processing step, allowing it to be easily inspected. Assuming a new enough dtc (which an earlier patch enforces), dtc will parse #line directives in its input file, and generate correct file and line numbers in error messages, even though cpp is unconditionally applied to its input file.

Soft resetting the UHH module causes instability issues on all OMAPs so we just avoid it. See OMAP36xx Errata i571: USB host EHCI may stall when entering smart-standby mode i660: USBHOST Configured In Smart-Idle Can Lead To a Deadlock On OMAP4/5, soft-resetting the UHH module can put it into Smart-Idle mode and lead to a deadlock. On OMAP3 this doesn't seem to be the case but still instabilities are observed on beagle (3530 ES1.0) if soft-reset is used. e.g. NFS root failures with Linux kernel.
