microblaze: Remove noMMU code

2020-11-26T15:39:35+00:00

This configuration is obsolete and likely none is really using it. That's
why remove it to simplify code.

Note about CONFIG_MMU in hw_exception_handler.S is left intentionally
for better comment understanding.

microblaze: Replace by

2020-11-10T17:07:09+00:00

The MicroBlaze platform code is not a clock provider, and just needs to
call of_clk_init().

Hence it can include  instead of .

treewide: Convert macro and uses of section(foo) to section("foo")

2020-10-25T21:51:49+00:00

Use a more generic form for __section that requires quotes to avoid
complications with clang and gcc differences.

Remove the quote operator # from compiler_attributes.h __section macro.

Convert all unquoted __section(foo) uses to quoted __section("foo").
Also convert __attribute__((section("foo"))) uses to __section("foo")
even if the __attribute__ has multiple list entry forms.

Conversion done using the script at:

mm: reorder includes after introduction of linux/pgtable.h

The replacement of  with  made the include
of the latter in the middle of asm includes.  Fix this up with the aid of
the below script and manual adjustments here and there.

mm: introduce include/linux/pgtable.h

2020-06-09T16:39:13+00:00

The include/linux/pgtable.h is going to be the home of generic page table
manipulation functions.

Start with moving asm-generic/pgtable.h to include/linux/pgtable.h and
make the latter include asm/pgtable.h.

microblaze: Kernel parameters should be parsed earlier

2020-02-24T11:19:42+00:00

Kernel command line should be parsed before cma initialization to be able
to get cma sizes from command line. That's why call parse_early_param()
before dma_continugous_reserve().

Unfortunately it can't be called earlier in machine_early_init() because
if earlycon is passed in the command line the parse_early_param() attempts
an ioremap which fails as the memory params are not set yet.

microblaze: no need to check return value of debugfs_create functions

2019-01-14T09:22:16+00:00

When calling debugfs functions, there is no need to ever check the
return value.  The function can work or not, but the code logic should
never do something different based on this.
