[U-Boot] drivers/net/phy/icplus.c delete reason

[Dvorkin Dmitry]

Hello Masahiro Yamada!

4 Aug 2014 in this mailing list you requested deletion of ICPLUS driver 
for a frequently used and cheap IP101A/G phy. Is there are better 
alternative PHY driver in U-Boot for this device? If not, could you 
patch it back?

The commit message is pretty explicit about the reason:

commit 368b4d2b49bbbf379d9334747fbbd2aaaafe4356
Author: Masahiro Yamada <yamada.m@jp.panasonic.com>
Date:   Mon Aug 4 08:11:37 2014 +0900

    drivers: net: remove dead drivers
    
    The following configs are not defined at all:
    
     - CONFIG_INCA_IP_SWITCH
     - CONFIG_PBL2800_ETHER
     - CONFIG_PHY_ICPLUS
    
    Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>

There is/was not a single board configuration in mainline U-Boot which
defined CONFIG_PHY_ICPLUS, i. e. the driver was just dead, unused
code.

So the PHY may be "frequently used and cheap", but the driver for it
has never been used in mainline, so we finally got rid of the dead
weight.

I can see no reason to adding it back - this can be easily done if
someone wants to actually use this driver, i. e. for example if you
submit a boad configuration which references it.

Best regards,

Wolfgang Denk

I assume you are mentioning commit 368b4d2b49bb (drivers: net: remove dead drivers).

I have no idea if the latest U-Boot code has an alternative PHY driver.

I am not willing to send the patch because I have no interest
in re-adding drivers I am not using.

If necessary for you, please feel free to send a patch to get it back.
(Please make sure there exists at least one board enabling the driver.
This is not my way, but the community's way.)
