Most boards use 8 or 16-bit access for the LED bank, se7206
needs 32. There's only 8 individual LEDs however, each with
a 'special' value in terms of logical ordering. Go FPGA, go!

The port routines were logically inverted, and the MRSHPC range had
no upper bound, causing 8 and 16-bit port I/O to get mangled.

Get the SH7343 and SH7770 stuff linking again. Both of these still

Signed-off-by: Paul Mundt <lethal@linux-sh.org>

The kgdb console code requires uart_set_options() and friends, which
are only provided by the serial core when console support is enabled.
These were sitting under CONFIG_SH_KGDB and resulted in a link error
when console support wasn't enabled, work that by rolling the console
routines under CONFIG_SH_KGDB_CONSOLE, which they should have been
all along.

HP6xx uses OFFCHIP_IRQ_BASE to know the base irq number where non
cpu interrupts should start. This define was in irq.h before, but
since rework got lost. It really belongs inside hd64461.h since
the hp6xx wont work without it.

This patch reworks the highlander irq code for r7780mp and r7785rp.
The same strategy as for the new R2D code is used here - the board
specific interrupts are now starting from HL_FPGA_IRQ_BASE. The code
for r7780rp is not touched due to lack of hardware.

Tested with CF, AX88796 on r7780mp and r7785rp. The touch switch
interrupt has also been tested on r7780mp.

- Adds IRQ_MODE_IRLnnnn_MASK using intc controller for IRL masking.
- Good old IRQ_MODE_IRLnnnn should not register any intc controller.

- the holding function is now disabled using ICR0.

We were abusing the resource size for the number of bits, this

This patch removes the old r2d config file named rts7751r2d_defconfig
and adds separate config files for the two r2d board versions. The two
new defconfigs are identical with the exception of board selection:

- rts7751r2dplus_defconfig selects CONFIG_RTS7751R2D_PLUS=y
- rts7751r2d1_defconfig selects CONFIG_RTS7751R2D_1=y

Please remember to update both files with r2d changes in the future.

This rips out some of the old spinlock and rwlock behaviour that the SH-2
