Hi,
This patch series introduces U-Boot support for NXP's LS1012A Packet Forwarding
Engine (pfe_eth). LS1012A uses hardware packet forwarding engine to provide
high performance Ethernet interfaces. The device includes two Ethernet ports.
Depends on https://patchwork.ozlabs.org/patch/704305
Regards
Calvin

This patch adds PFE driver into U-Boot.
Following are the main driver files:-
pfe.c: provides low level helper functions to initialize PFE internal
processor engines and other hardware blocks.
pfe_driver.c: provides probe functions, initialization functions
and packet send and receive functions.
pfe_eth.c: provides high level gemac, phy and mdio initialization
functions.
pfe_firmware.c: provides functions to load firmware into PFE
internal processor engines.

support pfe like starting or stopping the pfe, checking the health
of the processor engines and checking status of different unit inside
pfe.

To: u-boot
Ethernet support on all three LS1012A platforms(FRDM, QDS and RDB) is
enabled with this patch.
eth.c files for all 3 platforms contain board ethernet initialization
function and also function to reset phy.

Consider to reword for more explanation
Configure "xyz cacheable attributes, via scfg
PFE QoS settings configured as .... via scfg
dcfg ??

This is incomplete sentence, we should also tell what settings are being done.

Avoid hardcoding/magic numbers

Should remove hardcoded values , 0x524, 0x2000.
0x524 does not show up in the LS1012A RM (Rev 0). Please check once.
Also adding one liner telling what the above settings mean will help .

It seems reasonable to add support for each platform in individual patches.

Why this parameter in Kconfig.
This address is hard-coded per platform as defined in standard LSDK flash layout.

PFE IP has two MACs.
In the legacy driver model, we were registering two ethernet devices/interfaces, pfe_eth0 and pfe_eth1.
With the new driver model, I'm wondering whether we can do the same.
IIUC, U_BOOT_DEVICE corresponds to PFE IP on the LS1012A platform and struct eth_pdata corresponds to
each MAC. Is this correct?
If yes, how can we register two interfaces, pfe_eth0 and pfe_eth1? Please advice.
Thanks
Calvin
