2012-07-19net: fec_mxc: Fix setting of RCR for xMIIbenoit.thebaudeau@advans
At least on i.MX25, the RMII mode did not work, which is fixed by this patch. The MII_MODE bit of the FEC RCR register means xMII, i.e. 'not 7-wire', so set it accordingly. According to the xMII and 7-wire (aka GPSI) standards, full duplex should be available on xMII, but not on 7-wire, so set FCE accordingly. The FEC may support full duplex for 7-wire too, but the reference manual does not say that, so avoid an invalid assumption. Actually, the choice between half and full duplex also depends on the endpoint/switch/repeater configuration, so a config option could be added for that, but there has been no need for it so far.

2012-07-18ehci-hcd: fix external buffer cache handlingIlya Yanok
Buffer coming from upper layers should be cacheline aligned/padded to perform safe cache operations. For now we don't do bounce buffering so getting unaligned buffer is an upper layer error. We can't check if the buffer is properly padded with current interface so just assume it is (consider changing with in the future). The following changes are done: 1. Remove useless length alignment check. We get actual transfer length not the size of the underlying buffer so it's perfectly valid for it to be unaligned. 2. Move flush_dcache_range() out of while loop or it will flush too much. 3. Don't try to fix buffer address before calling invalidate: if it's unaligned it's an error anyway so let cache subsystem cry about that. 4. Fix end buffer address to be cacheline aligned assuming upper layer reserved enough space. This is potentially dangerous operation so upper layers should be careful about that.

2012-07-18ehci-hcd.c, musb_core, usb.h: Add USB_DMA_MINALIGN define for cache alignmentTom Rini
The USB spec says that 32 bytes is the minimum required alignment. However on some platforms we have a larger minimum requirement for cache coherency. In those cases, use that value rather than the USB spec minimum. We add a cpp check to <usb.h> to define USB_DMA_MINALIGN and make use of it in ehci-hcd.c and musb_core.h. We cannot use MAX() here as we are not allowed to have tests inside of align(...).

Otherwise, after booting the u-boot, and then inserting the SD card, the SD card can't be detected. For SDHC VVN2.3 IP, these bits are reserved, and SDCLKEN is used.
