New HAL for Olimex LPCX22XX boards

New HAL for Olimex LPCX22XX boards

[Sergei Gavrikov]

Hello

Two months ago (it so happened) I reworked and expanded HAL for six
almost the same boards from OLIMEX which are based on NXP LPC2214,
LPC2294 CPUs: http://bitbucket.org/tickling/olpcx22xx/wiki/Home

I entered generic package `olpcx22xx' and 6 targets (boards) around that
package: http://bitbucket.org/tickling/olpcx22xx/src/

The HAL startup code is a common part for the boards and was implemented
in C. There are a few working examples how to manage SPI, I2C, CAN buses
on the targets: http://bitbucket.org/tickling/olpcx22xx/wiki/Examples

I do not generate a patch just now, because the sources have not ECOSGPL
banners yet (it's easier to read them) and I do not know, would such a
replacement be interesting for community. I need a feedback.

FYI: You no need to install mercurial to overview the code, here are the
links for the direct downloads

http://bitbucket.org/tickling/olpcx22xx/get/tip.zip
http://bitbucket.org/tickling/olpcx22xx/get/tip.gz
http://bitbucket.org/tickling/olpcx22xx/get/tip.bz2

There is install script (install.sh) there which replaces old targets
and adds new ones.

A fresh look and tweak: all 6 (boards) + 1 (common) HALs were moved from
hal/arm/lpc2xxx into separate folder hal/arm/lpcx22xx/olpcx22xx/*. There
is not forest in arm/lpc2xxx anymore. It seemed for me that likes AT91
board variants now.

The below are freshmeat now. All templates: "redboot" {RAM,ROM,ROMRAM},
"default", and "net" were rebuilt to test the tweak (new HAL tree
arrangment).

And I forget one thing. LPC-E2294 Rev. B has Davicom DM9000 ethrenet
controller. My ethernet driver for the board needs this patch

This request is not applied still
