usb: gadget: lpc32xx_udc: Fix compatibility with STOTG04

The STOTG04 is an replacement for ISP1301.

Most of the registers on STOTG04 are the same as on ISP1301, but the
register ISP1301_I2C_OTG_CONTROL_2 (address 0x10) doesn't exist on the
ST part.

This is a work around for this by using the interrupt source register
should behave the same on both parts and has the needed information.

When support for frame buffer is disabled and MMC enabled, fdi3250.c
will not compile because MMC conditional compile construct mistakenly

ethernet:lpc32xx: Ethernet PHY timeout fix

The lpc_mdio_read() function returns an EIO before the final
lpc_net_hard_start_xmit() is called. It turns out that this is because
jiffies rolls over 5 minutes after boot. On a build with my gcc-4.6.1
toolchain, the phy just happens to get polled at a point when jiffies is
0xFFFFFFF8. Timeout therefore becomes +2 and the timeout comparison
fails immediately. The function returns an error and does not set
LPC_ENET_MCMD back to 0. I guess this means that the phy can no longer
receive packets, hence the crc errors. The atached patch fixes the

lpc32x0: nand: Workaround for NAND data loss issue

Temporary workaround for DMA/NAND support. There seems to be an issue
when using dma_map_single for NAND buffers in very rare cases. When this
issue happens, the NAND data will be corrupted. This tends to happen only when
under heavy NAND load. For now, keep this define enabled.
