This patch adds following clocks: "usbh.0_clk" and "usbh.1_clk". They are used
by ehci and ohci drivers for SPEAr3xx usb host devices.

'make dtbs' compiles all dtbs for a family. For this we need to add entries for
all board dtb's in Makefile.boot file. This patch does it.

For better print logs/messages, it is advisable to use pr_*() routines instead
of directly calling printks. This patch removes direct calling of printks for
spear3xx.

From: Viresh Kumar @ 2012-03-29 10:41 UTC (permalink / raw)
To: linux-arm-kernel, arnd
Cc: devicetree-discuss, spear-devel, viresh.linux, sr, plagnioj
This patch adds a generic target for SPEAr3xx machines that can be configured
via the device-tree. Currently the following devices are supported via the
devicetree:
- VIC interrupts
- PL011 UART
- PL061 GPIO
- PL110 CLCD
- SP805 WDT
- Synopsys DW I2C
- Synopsys DW ethernet
- ST FSMC-NAND
- ST SPEAR-SMI
- ST SPEAR-KEYBOARD
- ST SPEAR-RTC
- ARASAN SDHCI-SPEAR
- SPEAR-EHCI
- SPEAR-OHCI
Other peripheral devices will follow in later patches.
This also removes IO_ADDRESS macro and creates 16 MB static mappings instead of
4K for individual peripherals. This is done to have efficient TLB lookup for any
I/O windows that are located closely together. ioremap() on this range will
return this mapping only instead of creating another.

Recently device tree support is added for SPEAr3xx & SPEAr6xx and we must
upgrade defconfig for that to get compiled. This patches does it.
There are few more rearrangements done in defconfig automatically, when i run
make savedefconfig.
