| * | | ARM: i.MX6ul: Add SoC specific lowlevel_init functionSascha Hauer2017-10-176-2/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On i.MX6ul(l) (Cortex A7) We have to set the SMP bit before enabling the caches, otherwise they won't work. Add a SoC specific lowlevel_init function to be called by the i.MX6ul(l) boards. Since this is a quirk of the Cortex A7 core we put the functionality into a separate function to be reused by other Cortex A7 cores. Change existing i.MX6ul(l) boards to use the new initialisation function. It seems this is only needed when booting from USB, in other boot modes the ROM will already have done the initialisation.

| * | | scripts: imx imx-usb-loader: Fix last transfer error messageSascha Hauer2017-09-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When doing memory read transfers there will always be 64 bytes transferred, even when less bytes are requested. This is expected and there is a test skipping the error message in this case. The test is wrong though since cnt is not decremented and will never be equal to rem. Fix the test so that verifying memory does not give a bogus error message. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

The 'backend-storage-type' node is optional. Its default depends on the capability of the used backend memory, which means "circular" or NULL. The latter defaults to 'direct' in the routines. If it is NULL, the devicetree fixup routine skips exporting a 'backend-storage-type' node to the kernel's devicetree. But currently if the 'backend-storage-type' node is explicitly given as 'direct', it will be skipped silently and set to NULL instead. In this case the user of the 'barebox-state' tool then ends up with the warning: "No backend-storage-type found, using default" which is annoying, because it was given. Storing the given value will still use a NULL if the 'backend-storage-type' node isn't defined, but stores everything else if it is defined. Then the 'backend-storage-type' node is present in the kernel's devicetree as well. Signed-off-by: Juergen Borleis <jbe@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
