a89c33db96 General help message cleanup
Many of the help messages were not really helpful; for example, many
commands that take no arguments would not print a correct synopsis
line, but "No additional help available." which is not exactly wrong,
but not helpful either.

Commit ``Make "usage" messages more helpful.'' changed this
partially. But it also became clear that lots of "Usage" and "Help"
messages (fields "usage" and "help" in struct cmd_tbl_s respective)
were actually redundant.

This patch cleans this up - for example:

Before:
	=> help dtt
	dtt - Digital Thermometer and Thermostat

	Usage:
	dtt         - Read temperature from digital thermometer and thermostat.

After:
	=> help dtt
	dtt - Read temperature from Digital Thermometer and Thermostat

	Usage:
	dtt

708cfb74b7 OMAP3 Turn on the GPIO bank clocks
The function and interface clocks for each GPIO bank, except the first, must
be explicitly turned on.  These are controlled by the config level defines
CONFIG_OMAP3_GPIO_n where n is from 2 to 6.

b54384e3ba arm: timer and interrupt init rework
actually the timer init use the interrupt_init as init callback
which make the interrupt and timer implementation difficult to follow

so now rename it as int timer_init(void) and use interrupt_init for interrupt

btw also remane the corresponding file to the functionnality implemented

as ixp arch implement two timer - one based on interrupt - so all the timer
related code is moved to timer.c

The board-types defined in struct omap3_sysinfo seem to be

board type as an argument; which is ignored.

This patch removes all uses of board-type, related definitions

Use the functions print_cpuinfo() and checkboard() to
display the cpu and board specific information.

These functions reuse content from the existing function
display_board_info() - which has been removed.

Also, updated the existig OMAP3 configurations to
define:
 - CONFIG_DISPLAY_CPUINFO
 - CONFIG_DISPLAY_BOARDINFO

This is due to the fact that current command uses long
