+Subject: ath79: Fix fallback to bootloader cmdline on empty DT bootargs
+
+The MIPS code is supposed to fall back to u-boots bootargs whenever the
+/chosen/bootargs property is missing. But this feature was accidentally
+disabled when the boot_command_line was initialized with an empty space
+just to work around problems with early_init_dt_scan_chosen.
+
+But this feature is necessary for some boards which have a dualboot
+mechanism and whose u-boot is calculating the correct partition at runtime
+without writing this information back to the u-boot-env.

++Subject: MIPS: Setup boot_command_line before plat_mem_setup
++
++Platforms using DT will typically call __dt_setup_arch from
++plat_mem_setup. This in turn calls early_init_dt_scan. When
++CONFIG_CMDLINE is set, this leads to its value being copied into
++boot_command_line by early_init_dt_scan_chosen. If this happens before
++the code setting up boot_command_line in arch_mem_init runs, that code
++will go on to append CONFIG_CMDLINE (via builtin_cmdline) to
++boot_command_line again, duplicating it. For some command line
++parameters (eg. earlycon) this can be a problem. Set up
++boot_command_line before early_init_dt_scan_chosen gets called such that
++it will not write CONFIG_CMDLINE in this scenario & the arguments aren't
++duplicated.

++Subject: MIPS: Fix CONFIG_CMDLINE handling
++
++Commit 8ce355cf2e38 ("MIPS: Setup boot_command_line before
++plat_mem_setup") fixed a problem for systems which have
++CONFIG_CMDLINE_BOOL=y & use a DT with a chosen node that has either no
++bootargs property or an empty one. In this configuration
++early_init_dt_scan_chosen() copies CONFIG_CMDLINE into
++boot_command_line, but the MIPS code doesn't know this so it appends
++CONFIG_CMDLINE (via builtin_cmdline) to boot_command_line again. The
++result is that boot_command_line contains the arguments from
++CONFIG_CMDLINE twice.
++
++That commit took the approach of simply setting up boot_command_line
++from the MIPS code before early_init_dt_scan_chosen() runs, causing it
++not to copy CONFIG_CMDLINE to boot_command_line if a chosen node with no
++bootargs property is found.
++
++Unfortunately this is problematic for systems which do have a non-empty
++bootargs property & CONFIG_CMDLINE_BOOL=y. There
++early_init_dt_scan_chosen() will overwrite boot_command_line with the
++arguments from DT, which means we lose those from CONFIG_CMDLINE
++entirely. This breaks CONFIG_MIPS_CMDLINE_DTB_EXTEND. If we have
++CONFIG_MIPS_CMDLINE_FROM_BOOTLOADER or
++CONFIG_MIPS_CMDLINE_BUILTIN_EXTEND selected and the DT has a bootargs
++property which we should ignore, it will instead be honoured breaking
++those configurations too.
++
++Fix this by reverting commit 8ce355cf2e38 ("MIPS: Setup
++boot_command_line before plat_mem_setup") to restore the former
++behaviour, and fixing the CONFIG_CMDLINE duplication issue by
++initializing boot_command_line to a non-empty string that
++early_init_dt_scan_chosen() will not overwrite with CONFIG_CMDLINE.
++
++This is a little ugly, but cleanup in this area is on its way. In the
++meantime this is at least easy to backport & contains the ugliness
++within arch/mips/.

++Subject: MIPS: cmdline: Clean up boot_command_line initialization
++
++Our current code to initialize boot_command_line is a mess. Some of this
++is due to the addition of too many options over the years, and some of
++this is due to workarounds for early_init_dt_scan_chosen() performing
++actions specific to options from other architectures that probably
++shouldn't be in generic code.
++
++Clean this up by introducing a new bootcmdline_init() function that
++simplifies the initialization somewhat. The major changes are:
++
++- Because bootcmdline_init() is a function it can return early in the
++ CONFIG_CMDLINE_OVERRIDE case.
++
++- We clear boot_command_line rather than inheriting whatever
++ early_init_dt_scan_chosen() may have left us. This means we no longer
++ need to set boot_command_line to a space character in an attempt to
++ prevent early_init_dt_scan_chosen() from copying CONFIG_CMDLINE into
++ boot_command_line without us knowing about it.
++
++- Indirection via USE_PROM_CMDLINE, USE_DTB_CMDLINE, EXTEND_WITH_PROM &
++ BUILTIN_EXTEND_WITH_PROM macros is removed; they seemingly served only
++ to obfuscate the code.
++
++- The logic is cleaner, clearer & commented.
++
++Two minor drawbacks of this approach are:
++
++1) We call of_scan_flat_dt(), which means we scan through the DT again.
++ The overhead is fairly minimal & shouldn't be noticeable.
++
++2) cmdline_scan_chosen() duplicates a small amount of the logic from
++ early_init_dt_scan_chosen(). Alternatives might be to allow the
++ generic FDT code to keep & expose a copy of the arguments taken from
++ the /chosen node's bootargs property, or to introduce a function like
++ early_init_dt_scan_chosen() that retrieves them without modification
++ to handle CONFIG_CMDLINE. Neither of these sounds particularly
++ cleaner though, and this way we at least keep the extra work in
++ arch/mips.
