As the sLD3 Boot ROM has a complex page table, it is difficult to
set up the debug UART with enabling it.  It will be much easier to
initialize the UART port after switching over to the straight-mapped
page table.

Commit 4b50369f ("ARM: uniphier: create early page table at
run-time") broke the ROM boot mode for PH1-sLD3 SoC, because the
run-time page table creation requires the outer cache register
access but the page table in the sLD3 Boot ROM does not straight-map
virtual/physical addresses.

The idea here is to check the current page table to determine if
it is a straight map table.  If not, adjust the outer cache register
base.

Commit "ecc30663 Fix board init code to respect the C runtime environment"
broke platform support for ppc4xx.
start.S prepares a stackframe that is later rendered unusable by appending
the reserved space for global data.
Instead the reserved space has to be put first. Then the stackframe can
be pushed.

When a target device is 0 bytes long, there's no point in exposing it to
the user. Let's just skip them.

Also, when an offset is passed into the efi disk creation, we should
remove this offset from the total number of sectors we can handle.

When using CONFIG_BLK, there were 2 issues:

  1) The name we generate the device with has to match the

TI's PCF8575 is a 16-bit I2C GPIO expander.The device features a
16-bit quasi-bidirectional I/O ports. Each quasi-bidirectional I/O can
be used as an input or output without the use of a data-direction
control signal. The I/Os should be high before being used as inputs.
Read the device documentation for more details[1].

This driver is based on pcf857x driver available in Linux v4.7 kernel.
It supports basic reading and writing of gpio pins.

Example of the existing bug is when calculated div = 16. After and
