Most board-*.c files read configuration data from the bootloader in
their .init_machine() function. This needs to happen earlier, at some
point before omap2_init_common_hw() is called. This is because a
future patch will use the bootloader serial console port information
to enable the UART clocks earlier, immediately after omap2_clk_init().
This is in turn necessary since otherwise clock tree usecounts on
clocks like dpll4_m2x2_ck will be bogus, which can cause the
currently-active console UART clock to be disabled during boot.

This patch changes for setting the padconf value for sys_nirq line
which is connected to T2 INTR1. This will fix the T2 keypad wakeup
issue on OMAP3 SDP.

OMAP tags are deprecrated so drop them.
Drop UART config data which decides which UARTs to enable during boot.
This is no longer necessary since serial core code disables clocks
after inactivity.
Background: with new UART idle code, all on-chip UARTs are idled using
a configurable inactivity timer (default 5 seconds.) After the
inactivity timer, UART clocks are disabled automatically.

Some OMAP3 boards (Beagle Cx, Overo, RX51, Pandora) have 2
SDRAM parts connected to the SDRC.
This patch adds the following:
- add a new argument of type omap_sdrc_params struct*
to omap2_init_common_hw and omap2_sdrc_init for the 2nd CS params
- adapted the OMAP boards files to the new prototype of
omap2_init_common_hw
- add the SDRC 2nd CS registers offsets defines
- adapt the sram sleep code to configure the SDRC for the 2nd CS
Note: If the 2nd param to omap2_init_common_hw is NULL, then the
parameters are not programmed into the SDRC CS1 registers
Tested on 3430 SDP and Beagleboard rev C2 and B5, with
suspend/resume and frequency changes (cpufreq).

Add timing data for the Qimonda HYB18M512160AF-6 SDRAM chip, used on
the OMAP3430SDP boards.

Convert the board-rx51 smc91x code to be generic and make
the boards to use it. This allows future recalculation of the
timings when the source clock gets scaled.
Also correct the rx51 interrupt to be IORESOURCE_IRQ_HIGHLEVEL.
Thanks to Paul Walmsley <paul@pwsan.com> for better GPMC timing
calculations.
