Few registers and bits were added by Cadence and
they were not updated in the headers.
Take the latest definitions as defined in Linux
header (5.1) that also includes some comments
about existing registers.
One register was improperly named (UR), fix that.

macb.h provides macros for reading/setting bitfields,
in macb registers and descriptors. use that instead
of redefining them in the source file.

This patch adds support for the sgmii phy interface,
available only to DM users, dictated by current driver
design.

GEM support higher DMA burst writes/reads than the default (4).
add configuration structure with dma burst length so it could be
applied later to DMA configuration.

DMA configuration was heavily dependent on the HW
defaults, add function to properly set the required
fields, including the new dma_burst_length.

This is breaking the build. "UR" is still referred to in
drivers/net/macb.c line 805.
Did you build test this?

Well of course, but apparently I screwed this one in rebasing, prior to submit.
Didn't run buildman afterwards. sorry.
Will issue a revised patchset.
Sorry.

Actually, now that I look at this. it looks fine. the patch replaces
the line you mentioned:
https://patchwork.ozlabs.org/patch/1114041/
Can take a look ?

Just cherry-picked to a brand new master branch. there are no UR left
on the file
and it compiles correctly.
Did you apply something else beforehand ?

One of them is even in the context of this patch...
- gem_writel(macb, UR, 0);
+ gem_writel(macb, USRIO, 0);
#else
#if defined(CONFIG_RGMII) || defined(CONFIG_RMII)
gem_writel(macb, UR, GEM_BIT(RGMII));
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ This right here, and another
a few lines later.

Face palm
I tested with SGMII, that's why it worked on my setup.
I'll fix it shortly, sorry for the trouble :)

DMA configuration was heavily dependent on the HW
defaults, add function to properly set the required
fields, including the new dma_burst_length.
