The current value timer_rate_hz causes a problem with function
timer_get_us() from lib time and then an issue with
readx_poll_timeout() function.
With corrected value for tbclk() = timer_rate_hz = CONFIG_SYS_HZ_CLOCK
the weak functions in lib timer can be used:
- get_timer()
- __udelay()
So the specific function in this file are removed.

U-boot proper signature is not verified by SPL on most platforms
even config SPL_FIT_SIGNATURE is enabled. Only fsl-layerscape
platform support secure boot in platform specific code. So
verified boot cannot be achieved if u-boot proper is loaded by
SPL.
This patch add signature verification to u-boot proper images
when loading FIT image in SPL. It is tested on Allwinner bananapi

This converts the following to Kconfig:
CONFIG_CONS_INDEX
We have existing entries for this option in a number of places, with
different guards on them. They're also sometimes used for things not
directly inside of the serial driver. First, introduce a new symbol to
guard the use of CONFIG_CONS_INDEX, so that in the case where we don't
need this for the serial driver, but for some other use, we can still do
it. Next, consolidate all of these into the single entry in
drivers/serial/Kconfig. Finally, introduce CONS_INDEX_[023456] so that
we can imply a correct value here to make the defconfig side of this
smaller.

It is safe to always setup the pinmux for UART1 and UART3 to be used in
early_padconf and then if these pins are needed later on, they will be
re-muxed. This allows us to drop the usage of CONFIG_CONS_INDEX here.

Remove busy looping during watchdog reset.
Each polling of W_PEND_WTGR bit ("finish posted
write") after watchdog reset takes 120-140us
on BeagleBone Black board. Current U-Boot code
has watchdog resets in random places and often
there is situation when watchdog is reset
few times in a row in nested functions.
This adds extra delays and slows the whole system.
Instead of polling W_PEND_WTGR bit, we skip
watchdog reset if the bit is set. Anyway, watchdog
is in the middle of reset *right now*, so we can
just return.
This noticeably increases performance of the
system. Below are some measurements on BBB:
- DFU upload over USB 15% faster
- fastboot image upload 3x times faster
- USB ep0 transfers with 4k packets 20% faster

serial# variable is needed to show the device correctly in "fastboot

mode) connected to single host and want to choose which one to flash.
We can't use omap_die_id_serial() for this, because AM335x lacks
DIE_ID, as can be seen from AM335x TRM. Let's do next:
- reuse board_serial variable (obtained from EEPROM in
set_board_info_env() function) to set serial#
- if board_serial is "unknown", reuse ethaddr variable to set serial#
