In the recent change to the reset function API (commit
7b6d864b48), the mode argument changed from a
char to an enum. lpc23xx_restart() only handles REBOOT_SOFT and REBOOT_HARD,
but the new kernel code emits REBOOT_COLD (0) on reboots now which leads to
lpc32xx simply not rebooting (but halting).
This patch fixes this by just resetting unconditionally as on other platforms
(e.g. mach-bcm2835).
Pulling lpc32xx_watchdog_reset() into lpc23xx_restart() since the while() in
lpc23xx_restart() is part of the procedure anyway and lpc32xx_watchdog_reset()
isn't used anywhere else anymore.

When a link is already up, the following sequence makes the kernel
block completely:
ip link set dev eth0 down

This is because on suspended phy, the following lines
__lpc_eth_reset(pldat);
__lpc_eth_init(pldat);
make the LPC ethernet core block (see LPC32x0 manual). The PHY needs to be

When irq_of_parse_and_map() returns an error, it does as zero. But in
mmc_spi_get_pdata(), the error return case is compared against NO_IRQ.
This might work where NO_IRQ is zero (defaults to zero when undefined,
as on MIPS) but not where NO_IRQ is different, e.g. on ARM where it's -1.

On transactions with n>=2 bytes, the controller actually wrongly clocks in n+1
bytes. This is caused by the (wrong) assumption that RFE in the Status Register
is 1 iff there is no byte already ordered (via a dummy TX byte). This lead to
the implementation of synchronized byte ordering, e.g.:
Dummy-TX - RX - Dummy-TX - RX - ...
But since RFE actually stays high after some Dummy-TX, it rather looks like:
Dummy-TX - Dummy-TX - RX - Dummy-TX - RX - (RX)
The last RX byte is clocked in by the bus controller, but ignored by the kernel
when filling the userspace buffer.
This patch fixes the issue by asking for RX via Dummy-TX asynchronously.
