Existing ctype checks are implemented using a 256 byte lookup table,
allowing each character to be in any of 8 character classes. Since there
are 8 existing character classes without the blank class, I implemented
isblank without using the lookup table.  Since there are only two blank
characters - tab and space - this is a more reasonable approach than
doubling the size of the lookup table to accommodate one more class.

mx3fb.c was based on CONFIG_LCD and is moved by this patch to
CONFIG_VIDEO, which has greater freedom in selecting videomodes
even at runtime.

This renders the accumulating list of display defines
(CONFIG_DISPLAY_VBEST..., CONFIG_DISPLAY_C057...) obsolete as
these may be setup through env variables:

uboot> setenv mydisplay 'video=ctfb:x:240,y:320,depth:16,mode:0,pclk:185925,
	le:9,ri:17,up:7,lo:10,hs:1,vs:1,sync:100663296,vmode:0'
uboot> setenv videomode ${mydisplay}

This commit also fixes the board config files for qong and
imx31_phycore boards as needed. The videomode settings of
previously supported displays are added to CONFIG_EXTRA_ENV_SETTINGS
now. CONFIG_SYS_MALLOC_LEN for imx31_phycore board is increased
to make the frame buffer allocation working with the changed
driver.

The framebuffer driver for MX5 is based on CONFIG_LCD.
In the current implementation, there is a serious bug
because the required memory is allocated before
relocation, but the driver knows only later which is
the resolution of the display. The patch switches the driver
to CONFIG_VIDEO and the memory is allocated by the driver itself.

We also need to switch the vision2 board code and config file
in the same commit so that this commit will be bisectable.

This Jz4740-based clamshell device does not use NOR flash to boot.
The initial bring-up assumes that U-Boot is directly loaded into SDRAM
using USB boot tool, and starts from 0x80100000.

About USB boot tool
-------------------

Jz4740 is one of the XBurst processors with USB boot functionality
supported.  The CPU can boot from a small ROM in the LSI, initialize
CPU and USB module, then wait for USB commands from the USB host.
We can send 8 KB binary data to the CPU cache using USB boot tool.

USB boot tool is available to the public at Ingenic website.  Also
there is an alternative Debian package named xburst-tools.

We really shouldn't be overwriting bat registers with translation enabled,
especially when we're executing code using one of them for translating
the current instruction stream.  Instead, disable address translation
while doing the final BAT setup.

In order to do this, setup_bats has to move back to asm code, because we
require translation to be enabled to have a stack for C code.  The yucky
thing about that is that the assembler doesn't like ULL so we have to
switch to using HIGH/LOW pairs for physical addresses that are > 32 bits
in length.

Interactive DDR debugging provides a user interface to view and modify SPD,
DIMM parameters, board options and DDR controller registers before DDR is
initialized. With this feature, developers can fine-tune DDR for board
bringup and other debugging without frequently having to reprogram the flash.

To enable this feature, define CONFIG_FSL_DDR_INTERACTIVE in board header
file and set an environment variable to activate it. Syntax:

setenv ddr_interactive on

After reset, U-boot prompts before initializing DDR controllers
FSL DDR>

The available commands are
print      print SPD and intermediate computed data
reset      reboot machine
recompute  reload SPD and options to default and recompute regs
edit       modify spd, parameter, or option
compute    recompute registers from current next_step to end
next_step  shows current next_step
help       this message
go         program the memory controller and continue with u-boot

The first command should be "compute", which reads data from DIMM SPDs and
board options, performs the calculation then stops before setting DDR
controller. A user can use "print" and "edit" commands to view and modify
anything. "Go" picks up from current step with any modification and
compltes the calculation then enables the DDR controller to continue u-boot.
"Recompute" does it over from fresh reading.

This test is similar to the actual POST memory test but quicker and
far less complete. It checks the address and data lines and then only
tests some regularly placed sub regions of the RAM.
This can be useful when we want to test the RAM but we do not have enough
time to run the full memory test.

The POST memory test code was rearranged in order to avoid code duplication
between the two tests but the memory test functionnality remains the same.
