| * miidev: consistent md and mw on phy regsJohannes Stezenbach2012-06-301-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The dump generated by "md -w -s /dev/phy0" suggests individual registers need to be addressed by byte offset, not by register number. E.g. to set the autonegotiation advertisement register for 10Mbit only, use "mw -w -d /dev/phy0 8+2 0x0061". The current mix of offset == register number, but count == byte count is unintuitive. Also, to be consistent with "md" on /dev/mem, round up the count so "8+1" also works to access one register. However, no attempt is made to do read-modify-write single byte writes.

| * | | | Change byte order detection mechanism to kernel styleSascha Hauer2012-06-282-5/+7
| |/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Linux Kernel defines only one of __LITTLE_ENDIAN and __BIG_ENDIAN. Endianess can then be tested with #ifdef __xx_ENDIAN. Userspace always defined both __LITTLE_ENDIAN and __BIG_ENDIAN and byteorder can then be tested with #if __BYTE_ORDER == __xx_ENDIAN. As we tend to use a lot of Kernel code in barebox we switch to use the kernel way of determing the byte order. As this always causes a lot of confusion add a check to include/common.h to make sure only one of __LITTLE_ENDIAN and __BIG_ENDIAN is defined. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* / / / ehci: Fix resource sizeSascha Hauer2012-07-021-1/+1

This was assumed to be 0x40 in size. On OMAP though it is only 0x10 and then the hccr resource conflicts with the hcor resource which results in a non working ehci port on beagle and panda boards. This patch adds a nonintrusive workaround, it limits the hccr resource to 0x10, which then also works on OMAP. Later we should drop the multiple resources for the ehci port and make the resource as specified in the datasheets.
