PPC: Use r2 instead of r29 as global data pointer

2008-02-14T21:43:22+00:00

R29 was an unlucky choice as with recent toolchains (gcc-4.2.x) gcc
will refuse to use load/store multiple insns; instead, it issues a
list of simple load/store instructions upon function entry and exit,
resulting in bigger code size, which in turn makes the build for a
few boards fail.

Use r2 instead.

Fix Ethernet init() return codes

2008-01-10T00:06:02+00:00

Change return values of init() functions in all Ethernet drivers to conform
to the following:

    >=0: Success
    <0:  Failure

All drivers going forward should return 0 on success.  Current drivers that
return 1 on success were left as-is to minimize changes.

Fix and optimize MII operations on FEC (MPC8xx) controllers

2008-01-09T13:52:04+00:00

This patch fixes several issues at least on a MPC885 based system with two
FEC interfaces used in MII mode.

1. PHY discovery should first read PHY_PHYIDR2 register and only then
   PHY_PHYIDR1 like cpu/mpc8xx/fec.c::mii_discover_phy() does it,
   otherwise the values read are wrong. Also notice, that PHY discovery
   cannot work on MPC88x / MPC87x in setups with both FECs active at all
   in its present form, because for both interfaces the registers from FEC
   1 are used to communicate over MII.

2. Remove code duplication for resetting the FEC by isolating it into a
   separate function.

3. Initialize MII on FEC 1 when communicating over FEC 2 in fec_init().

4. Optimize mii_init() to only reset the FEC 1 controller once.

5. Fix a typo in mii_init() using index i instead of j thus potentially
   leading to unpredictable results.

cpu/mpc/ : Augment CONFIG_COMMANDS tests with defined(CONFIG_CMD_).

2007-07-03T22:23:18+00:00

This is a compatibility step that allows both the older form
and the new form to co-exist for a while until the older can
be removed entirely.

All transformations are of the form:
Before:
    #if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT)
After:
    #if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT) || defined(CONFIG_CMD_AUTOSCRIPT)
