This was only used by the old inflate code, which isn't used
anymore by ARM.

Add this define to machines which really make use of
this function.

As only the minority of the machines uses arch_decomp_setup,
ifdef it out when not needed, to avoid needless defines in
all uncompress.h files.
Machines using this feature should add
in their uncompress.h headers.

I guess this was removed by git-commit.

This is a place that needs some care for multi-SoC. I don't know if
there are any ideas how to handle it, but using a cpp symbol won't work
I guess. So I think it's not worth to touch arch_decomp_setup without
solving the multi-SoC case.
Best regards

Now that the decompressor code only calls this function
when ARCH_HAVE_DECOMP_SETUP is defined, the unused empty
declarations can go away.
As an added bonus, over 30 comments stating "nothing to do"
get deleted, making the ARM arch more busy than ever.

Why do we need this new define? arch_id in this file has only been a
local parameter to a function, and with your changes it looks like all
references have been removed.

Ignore this - it's needed for calls to arch_decomp_setup().

Now that misc.c only holds functions related to printout
during decompression, rename it accordingly.

This adds the ucuart struct which should be a sufficient
description for being able to print through a serial port.
Generic versions of putc() and flush() using ucuart are also
added, along with initialization helpers, one specifically
for the 8250 family UART and one for the AMBA01X PrimeCell.
The port structure is not declared statically, but inited
through arch_decomp_setup() to have it in the .bss area,
thus in RAM.

Ditto.

I don't like this - this is *not* part of the kernel, it's part of a
separate execution environment which may not contain everything required
for a functional macros in this header file.

Finally convert the machine-specific uncompress.h files
to use the ucuart driver. This gets rid dozens of
re-implementations for handling an UART.
Samsung stuff needs re-thinking.

Now that the initialization of the ucuart uses arch_decomp_setup,
almost all machines use it, so make this the default behaviour.

As most of the machines now use the ucuart driver, let's make
this the default implementation, and mark those which do not
conform with ARCH_UCUART_NONGENERIC.

Bring some standard into the files:
- uncompress.h should only be included once, don't hide an
error with the header guards
- If the copyright banner is longer than the real content,
or the file has been mostly rewritten, just stick
a short-form GPl notice on top

From: Zoltan Devai @ 2011-10-23 21:10 UTC (permalink / raw)
To: linux-arm-kernel
Allow the static decompress UART setup in uncompress.h
files to be overridden with an ucuart description in DT.
At a later stage, this may also allow to skip the
inclusion of uncompress.h files on arches which are DT-only,
to get rid of these files completely.

This needs to be reviewed by DT people.

Nice patch series!
I like this approach, because it allows us to:
1. Use this DT entry entry for earlyprintk, and then
CONFIG_DEBUG_LL can be separated from all this
2. CONFIG_DEBUG_LL can now be reserved for the low-level
debugging when bringing up new SoC/board etc
3. This allows seeing uncompress errors on unsupported
boards, which is important when working on multiarch support
4. With this series we can turn earlyprintk into something
that can be compiled into production kernels too
I have not looked through the patch series if it uses still
CONFIG_DEBUG_LL somewhere, but if it does, it should be
separated from that.
Cheers,
Tony

Short description for mach maintainters on how to use the
ucuart driver. It is in-line in the print.c file, as they will
probably look there for any compile/link errors caused by
their decompressor UART setup.
