We don't allow CamelCase identifiers in U-Boot. Variable names must be
all lower case. Please fix globally.

NAK. We don't allow that such decisions are enforced on the end user.
Feel free to add such a default setting to your environment, but leave
the user the freedom to decide otherwise.

NAK. Please always use I/O accessors to access device registers and
the like. Please fix globally.

NAK. We do not allow network settings in the default configuration.
They may make sense to you, but they do not make sense to most others.

Adds support for the ARM quad-core Cortex-A9 processor.
This system includes a motherboard(Versatile Express),
daughterboard(Coretile), and an SOC(Cortex-A9 quad core).
The serial port, ethernet, and flash systems work with
these additions.
The 2nd patch fixes a bug in the "set baudrate xxx" functionality.
---
Version 2 - Removed unneeded multi-core low_level setup code.
Version 3 -
Patch 1)
1) Fixups from Wolfgang's code review:
- Remove CamelCase variable definitions, keep lists sorted, tab indents
only, remove trailing empty lines, remove unneeded configuration options,
use I/O accessors, added while(1) loop in reset command
2) Simplified board_init declarations
3) Added CONFIG_INITRD_TAG declaration
4) Removed unneeded assembly directives from Makefile
Patch 2)
1) Replaced IO_WRITE and IO_READ calls in serial_pl01x.c with calls to
readl() and writel(). Fixed commenting and CamelCase problems.

Adds support for the ARM quad-core Cortex-A9 processor. This system
includes a motherboard(Versatile Express), daughterboard(Coretile),
and SOC(Cortex-A9 quad core). The serial port, ethernet, and flash
systems work with these additions. The naming convention is:
SOC -> CortexA9 quad core = ca9x4
daughterboard -> Coretile = ct
motherboard -> Versatile Express = vxp
This gives ca9x4_ct_vxp.c as the board support file.

The pl01x serial driver was lacking the code to switch baudrates from the
command line. Fixed by simply saving the new baudrate and calling
serial_init() again. Also fixed CamelCase variables, I/O accessors and
comment style.

Adds support for the ARM quad-core Cortex-A9 processor.
This system includes a motherboard(Versatile Express),
daughterboard(Coretile), and an SOC(Cortex-A9 quad core).
The serial port, ethernet, and flash systems work with
these additions.
The 2nd patch fixes a bug in the "set baudrate xxx" functionality.
---
Version 2 - Removed unneeded multi-core low_level setup code.
Version 3 -
Patch 1)
1) Fixups from Wolfgang's code review:
- Remove CamelCase variable definitions, keep lists sorted, tab indents
only, remove trailing empty lines, remove unneeded configuration options,
use I/O accessors, added while(1) loop in reset command
2) Simplified board_init declarations
3) Added CONFIG_INITRD_TAG declaration
4) Removed unneeded assembly directives from Makefile
Patch 2)
1) Replaced IO_WRITE and IO_READ calls in serial_pl01x.c with calls to
readl() and writel(). Fixed commenting and CamelCase problems.
Version 4 -
1) Refactored to work with the "next" branch
2) Fixed a bug in the 2nd flash bank definition

Adds support for the ARM quad-core Cortex-A9 processor. This system
includes a motherboard(Versatile Express), daughterboard(Coretile),
and SOC(Cortex-A9 quad core). The serial port, ethernet, and flash
systems work with these additions. The naming convention is:
SOC -> CortexA9 quad core = ca9x4
daughterboard -> Coretile = ct
motherboard -> Versatile Express = vxp
This gives ca9x4_ct_vxp.c as the board support file.

To: u-boot
From: Matt Waddel <matt.waddel@linaro.org>
The pl01x serial driver was lacking the code to switch baudrates from the
command line. Fixed by simply saving the new baudrate and calling
serial_init() again. Also fixed CamelCase variables, I/O accessors and
comment style.

Matt Waddel (2):
Adds support for the ARM quad-core Cortex-A9 processor.
This system includes a motherboard(Versatile Express), daughterboard
(Coretile), and SOC(Cortex-A9 quad core). The serial port, ethernet,
and flash systems work with these additions. The naming convention
is:
SOC -> CortexA9 quad core = ca9x4
daughterboard -> Coretile = ct
motherboard -> Versatile Express = vxp
This gives ca9x4_ct_vxp.c as the board support file.
The 2nd patch fixes a bug in the "set baudrate xxx" functionality and
fixes some of the code problems like CamelCase and IO accessors.
---
Version 2 -
Removed unneeded multi-core low_level setup code.
Version 3 -
Patch 1)
1) Fixups from Wolfgang's code review:
- Remove CamelCase variable definitions, keep lists sorted, tab indents
only, remove trailing empty lines, remove unneeded configuration options,
use I/O accessors, added while(1) loop in reset command
2) Simplified board_init declarations
3) Added CONFIG_INITRD_TAG declaration
4) Removed unneeded assembly directives from Makefile
Patch 2)
1) Replaced IO_WRITE and IO_READ calls in serial_pl01x.c with calls to
readl() and writel(). Fixed commenting and CamelCase problems.
Version 4 -
1) Refactored to work with the "next" branch
2) Fixed a bug in the 2nd flash bank definition
Version 5 -
1) Refactored to apply to the tip of git tree.
2) Improved the environment settings and added the run command option

These 2 patches have been hanging around for a while and
I've been pulling them along with the trunk changes.
They've already been reviewed a couple of times, and there
was one Tested-by a while back. I was wondering if there
is anything else I need to do get them merged. I'm concerned
they won't make it in before the merge window closes again.
Thanks,
Matt

Applied to u-boot-arm (dropping the V3 version).
But please: make sure to keep threading workign, and add a change log
to the patches.

From: Matt Waddel <matt.waddel@linaro.org>
The pl01x serial driver was lacking the code to switch baudrates from the
command line. Fixed by simply saving the new baudrate and calling
serial_init() again. Also fixed CamelCase variables, I/O accessors and
comment style.
