Commit 5d2c154 (IMX: MX31: Cleanup include files and drop nasty #ifdef in drivers)
renamed mx31-imx-regs.h to imx-regs.h.

Change the file label accordingly.

Use the same method of the Linux kernel to print the MX31 silicon version on
boot.

Tested on a MX31PDK with a 2.0 silicon, where it shows:

CPU:   Freescale i.MX31 rev 2.0 at 531 MHz
Signed-off-by: NFabio Estevam <fabio.estevam@freescale.com>

As exception among the i.MX processors, the i.MX31 has headers
without general names (mx31-regs.h, mx31.h instead of imx-regs.h and
clock.h). This requires several nasty #ifdef in the drivers to
include the correct header. The patch cleans up the driver and
renames the header files as for the other i.MX processors.

The patch add CONFIG_HW_WATCHDOG to be used
with the internal watchdog timer of the MX31
processor. Two function are exported for the
board maintainers:
	mxc_hw_watchdog_enable
	mxc_hw_watchdog_reset

The board maintainer can decide to use mxc_hw_watchdog_reset as
hw_watchdog_reset, or to implement his own function to reset
the watchdog.
The watchdog timer can be configured with CONFIG_SYS_WD_TIMER_SECS
(value in seconds). The MX31 allows values between 0.5
(CONFIG_SYS_WD_TIMER_SECS = 0) and 128 seconds.

I ran into a problem where the reset was failing except when I enabled
debugging support.  After talking with Garret Swalling at Spansion I
was told that the GL-N series of devices require a 500ns wait for the
reset to complete.  The below patch adds a 1us delay after all reset
commands.

The M29W800DT parts also report their geometry with the sector layout
reversed.  So add that ID to the flash_fixup_stm function.

Otherwise, we get:

This fixes two bugs with comparison of redundant environment flags on
read.

flag0 and flag1 in fw_env_open() were declared signed instead of
unsigned char breaking BOOLEAN mode "== 0xFF" tests and in INCREMENTAL
mode the wrong environment would be chosen where the flag values are
127 and 128 (either way round). With both flags over 128, both signs
flipped and the logic worked by happy accident.

Also there was a logic bug in the INCREMENTAL test (after signedness was
fixed) in the case flag0=0, flag1=255, env 1 would be incorrectly chosen.

Fix both of these.
