MPC8266ADS patch

MPC8266ADS patch

[Curtis, Allen]

Here is a patch to make MPC8266ADS its own platform. Instead of creating a
new platforms/ads8266.h header, I could have inserted conditional compiles
into the ads8260.h for the memory map differences.

Note: This is enough to get the kernel to build, boot and run. There are
other issues that still need to be addressed.

Thanks

Will the "other issues to be addressed" cause the need for more definitions
or further #ifdefs in the existing file?  If so, let's just go ahead and
create the new file now and just add to it later.

Thanks.

Re: MPC8266ADS patch

[Rakesh Jagota]

hi,

i am trying to integrate IR keyboard to a custom board.
I am having serial console on the boad.

when i am calling handle_scancode in keyboard.c
this statement,

 void handle_scancode(unsigned char scancode, int down)
 {
 -----
 tty = ttytab? ttytab[fg_console]: NULL;
 ;
 }

returns tty=NULL

          __init kbd_init(void)
 {
  ------
  ------
  ttytab = console_driver.table;
 }

in this fuction also ttytab[fg_console] is still NULL

Is serial console is enough to keyboard?

i have frambuffer support on my board. (without HW
      graphic accelerator)

How to enable the frambufffer console on my board.
      (i am attaching the config file below)

Re: PPC 405

[Rakesh Jagota]

hi all,
We are using linux from montvista (linux-2.4.17_mvl21). We are
working on custom design board based on vulcan chip -stbx25xx
(IBM405 ppc). The board name is redwood6.

I am getting the following values

in fuction:  handle_scancode()
fg_console=0
ttytab[fg_console]=NULL;

what change i have  to do to get the keys on my serial console.
Thanks in advance
Rakesh

And, better yet, why not just pull all of the ADS8266 bits in _devel now
out to 2.4 proper?  (And, pretty please, for 2.6 as well? :))
