Subject: [PATCH AUTOSEL 6.3 6/7] powerpc/fsl_uli1575: Allow to disable FSL_ULI1575 support

From: Pali Rohár <[email protected]>

[ Upstream commit 22fdf79171e8509db54599fd2c05ef0022ee83f5 ]

ULI1575 PCIe south bridge exists only on some Freescale boards. Allow to
disable CONFIG_FSL_ULI1575 symbol when it is not explicitly selected and
only implied. This is achieved by marking symbol as visible by providing
short description. Also adds dependency for this symbol to prevent enabling
it on platforms on which driver does not compile.

Hi--

Just a heads up. This patch can cause build errors.
I sent a patch for these on 2023-APR-28:
https://lore.kernel.org/linuxppc-dev/[email protected]/

Michael, I think this is your area if I'm not mistaken.

Yes. The fix is in my fixes branch as:
536d948a8dee ("powerpc/fsl_uli1575: fix kconfig warnings and build errors")

But I don't think this commit (22fdf79171e8) really warrants going to
stable, it's a nice-to-have but doesn't fix any pressing bugs.

cheers

Exactly. And also this patch alone without 1/8 would not work as in 1/8
https://lore.kernel.org/all/[email protected]/ was
added static inline variant of function which is used when ULI is
disabled.
