a76cf2b65e memory: tegra: Remove downstream loadable mc-err driver
Downstream mc-err loadable module won't be able to print mc-err during
boot. Hence we are making this a static driver in kernel-oot.
Later on we need to update the upstream mc driver to incorporate the
changes.

2b75cb208d memory: tegra: Update mc-err driver as per latest flow
Update mc-err driver for t264 as per the latest flow provided by HW
team.
- Correct register offsets.
- Add mc-error handling flow for MCF, HUB, HUBC, SBS and MC Channel.
- Register interrupt handlers for interrupts from these different
MSS components.

0fe1f6b8b0 nvidia-t264: Fix missing-prototypes
The compiler option -Wmissing-prototypes is being enabled globally in
the upstream Linux kernel and this causes build failures. The build
failures occur because either the driver is missing an include file
which has the prototype or because the function is not declared
statically when it should be (ie. there are no external users).

Fix the various build failures that are seen when enabling
-Wmissing-prototypes.

aafa45a665 memory: tegra: Handle incorrect mc interrupt mask case
Cert-C is flagging following issue in mc-err code:
cert_exp33_c_violation: Using uninitialized value status_reg when
calling mc_ch_readl.

Fix the above issue by adding a default case for MC interrupt mask and
return from there by printing the error.

0c103ec66e memory: tegra: Add support for mc-err driver
Add support for mc-err driver on T264. Maintain driver similar to
current upstream mc-err driver, so that upstreaming diff for T264 would
be straight forward. Current IRQ handling logic is as follows:
- Read MCF int status from MCB
- Find out the MC channel responsible for generating error
- Read address register from that MC channel block to get the address
- Find out type of error from status register

Current implementation is as per the information received so far,
further updates will be made once HW team provide programming
guidelines.

66cb141d65 memory: tegra: fix coverity overflow defect
mc_readl() returns 32-bit value. The value is getting left-shifted by
17-bits which can cause overflow and loss of data.
Fix this by casting the return value of mc_readl() to u64.
