ca4d3e6746 MIPS: Add missing #inclusions of <linux/irq.h>
Add missing #inclusions of <linux/irq.h> to a whole bunch of files that should
really include it.  Note that this can replace #inclusions of <asm/irq.h>.

This is required for the patch to sort out irqflags handling function naming to
compile on MIPS.

The problem is that these files require access to things like setup_irq() -
which isn't available by #including <linux/interrupt.h>

d16f7093b6 MIPS: AR7: rewrite of cpmac_get_mac()
Shamelessly stealing wisdom from pasemi_mac.c, I found char2hex() could
be replaced with a single call to sscanf(), looks cleaner to me at
least.  The result is 100 bytes trimmed off the size of a compiled
cpmac_get_mac() and as an extra bonus it grumbles and gracefully fails
over to using random_ether_addr() when an attempt to parse an invalid
MAC address is made.

5d25b01cf9 MIPS: Introduce support for Platform definitions
Move platform specific definitions to the platfrom directories.

Each platform shall do the following:
1) include an entry in arch/mips/Kbuild.platforms
2) add relevant definitions to arch/mips/<platform>/Platform

This commits changes ar7 to the new scheme as an example.

Introducing a platform speecific Platfrom file has following advantages:
1) decentralization of platfrom definitions
2) simplification af arch/mips/Makefile
3) force all platfrom to build with -Werror (done in arch/mips/Kbuild)

[Ralf: Remove forgotten -Werror from AR7 Makefile]

154615d554 MIPS: AR7: Use correct UART port type
PORT_AR7 has the correct TRIG flag (UART_FCR_R_TRIG_00) as well as
UART_CAP_AFE being set. This fixes UART on TNETD7300 revision 0x02,
which would otherwise mangle some characters, no side effects on
other revisions.

142a2ceea7 MIPS: AR7: prevent race between clock initialization and devices registration
ar7_regiser_devices needs ar7_clocks_init to have been called first,
however clock.o is currently linked later due to its order in the Makefile,
therefore ar7_clocks_init always gets called later than ar7_register_devices
because both have the same initcall level. Fix this by moving
ar7_register_devices to the right initcall level.

Several static uninitialized variables are used in the scope of __init

little bit.

Also, a couple of lines with spaces instead of tabs were fixed.
