9 years agokconfig: switch to single .config configuration
Masahiro Yamada [Tue, 24 Feb 2015 13:26:20 +0000 (22:26 +0900)]
kconfig: switch to single .config configuration

When Kconfig for U-boot was examined, one of the biggest issues was
how to support multiple images (Normal, SPL, TPL).  There were
actually two options, "single .config" and "multiple .config".
After some discussions and thought experiments, I chose the latter,
i.e. to create ".config", "spl/.config", "tpl/.config" for Normal,
SPL, TPL, respectively.

It is true that the "multiple .config" strategy provided us the
maximum flexibility and helped to avoid duplicating CONFIGs among
Normal, SPL, TPL, but I have noticed some fatal problems:

[1] It is impossible to share CONFIG options across the images.
  If you change the configuration of Main image, you often have to
  adjust some SPL configurations correspondingly.  Currently, we
  cannot handle the dependencies between them.  It means one of the
  biggest advantages of Kconfig is lost.

[2] It is too painful to change both ".config" and "spl/.config".
  Sunxi guys started to work around this problem by creating a new
  configuration target.  Commit cbdd9a9737cc (sunxi: kconfig: Add
  %_felconfig rule to enable FEL build of sunxi platforms.) added
  "make *_felconfig" to enable CONFIG_SPL_FEL on both images.
  Changing the configuration of multiple images in one command is a
  generic demand.  The current implementation cannot propose any
  good solution about this.

[3] Kconfig files are getting ugly and difficult to understand.
  Commit b724bd7d6349 (dm: Kconfig: Move CONFIG_SYS_MALLOC_F_LEN to
  Kconfig) has sprinkled "if !SPL_BUILD" over the Kconfig files.

[4] The build system got more complicated than it should be.
  To adjust Linux-originated Kconfig to U-Boot, the helper script
  "scripts/multiconfig.sh" was introduced.  Writing a complicated
  text processor is a shell script sometimes caused problems.

Now I believe the "single .config" will serve us better.  With it,
all the problems above would go away.  Instead, we will have to add
some CONFIG_SPL_* (and CONFIG_TPL_*) options such as CONFIG_SPL_DM,
but we will not have much.  Anyway, this is what we do now in
scripts/Makefile.spl.

I admit my mistake with my apology and this commit switches to the
single .config configuration.

It is not so difficult to do that:

 - Remove unnecessary processings from scripts/multiconfig.sh
  This file will remain for a while to support the current defconfig
  format.  It will be removed after more cleanups are done.

 - Adjust some makefiles and Kconfigs

 - Add some entries to include/config_uncmd_spl.h and the new file
   scripts/Makefile.uncmd_spl.  Some CONFIG options that are not
   supported on SPL must be disabled because one .config is shared
   between SPL and U-Boot proper going forward.  I know this is not
   a beautiful solution and I think we can do better, but let's see
   how much we will have to describe them.

 - update doc/README.kconfig

More cleaning up patches will follow this.

will work fine for all mmc boot devices.

- 2 for 4bit - as an optional boot device (usually SD card slot)

And usually the boot order is defined by OM pin configuration,

- Odroid U3     - eMMC card insertion -> first boot from eMMC

Siarhei Siamashka [Sat, 21 Feb 2015 05:34:09 +0000 (07:34 +0200)]
sunxi: Machine id hack to prevent loading buggy sunxi-3.4 kernels

Right now U-Boot supports the CONFIG_OLD_SUNXI_KERNEL_COMPAT option,
which makes it go out of its way in limiting the selection of PLL clock
frequencies and PMIC voltages in order not to upset outdated buggy
sunxi-3.4 kernel releases. And if the CONFIG_OLD_SUNXI_KERNEL_COMPAT
option is not set, then booting such old kernels exhibits various
failures at runtime. This is very user unfriendly, and there were
already several incidents when people wasted their time being hit
by these runtime failures and trying to debug them.

The right solution is not to add hacks and workarounds to the mainline
U-Boot, but to fix these bugs in the sunxi-3.4 kernel. And in fact,
the updated sunxi-3.4 kernels already exist. Still we need to follow
the 'Principle of Least Surprise' and U-Boot needs to ensure that
the old buggy kernels are not getting happily booted when the
CONFIG_OLD_SUNXI_KERNEL_COMPAT option is not set. And this patch
addresses this particular issue.

This patch makes U-Boot store the 'compatibility revision' number in
the top 4 bits of the machine id and pass it to the kernel. The old
buggy kernels will fail to load with a very much googlable error
message on the serial console (the "r1 = 0x100010bb" part of it):

  "Error: unrecognized/unsupported machine ID (r1 = 0x100010bb)"

This error message can be documented in the linux-sunxi wiki with
proper explanations about how to resolve this situation and where
to get the necessary bugfixes for the sunxi-3.4 kernel.

The fixed sunxi-3.4 kernels implement a revision compatibility check
and clear the top 4 bits of the machine id if everything is alright.
By accepting the machine id with the bits 31:28 set to 1, the sunxi-3.4
kernel effectively certifies that it has the PLL5 clock speed and
AXP209 DCDC3 voltage fixes applied.

It is still possible to set the CONFIG_OLD_SUNXI_KERNEL_COMPAT option
in U-Boot if the user desires to use an outdated unpatched sunxi-3.4
kernel.

sunxi: Fix sun5i mbus speed when booting old kernels

Older linux-sunxi-3.4 kernels override our PLL6 setting with 300 MHz,
halving the mbus frequency, so set it to 300 MHz ourselves and base the
mbus divider on that.

ARM: prepare for moving SoC sources into mach-*

In U-boot, the directory structure, arch/$(ARCH)/cpu/$(CPU)/$(SOC)/
has been adopted except that $(CPU) is missing from some
architectures and $(SOC) is missing from some CPUs.

This structure did not fit very well in some cases.

[1] AT91

AT91 SoC family have been developed across some ARM processor
generations.  Generally speaking, some IPs are often re-used in the
same SoC family (same SoC vendor) even when the main processor is
updated.  As a result, a SoC-common directory is needed in the upper
level.  Currently, AT91 source files are placed as follows:

  arch/arm/cpu/arm920t/at91/*
  arch/arm/cpu/arm926ejs/at91/*
  arch/arm/cpu/armv7/at91/*
  arch/arm/cpu/at91-common/*

Once directories are split, the motivation for refactorings across
CPU directories is lost.  Some files in arm920t/at91/ and
arm926ejs/at91/ are so similar that they could be merged.

[2] Tegra

Tegra is a little bit special case where different CPUs are used for
SPL and the main U-boot.  To obey the arch/$(ARCH)/cpu/$(CPU)/$(SOC)
structure, the source files must be placed across the CPUs,
again SoC-common directory is necessary in the upper level.

Moreover, there are several families in Tegra: Tegra20, Tegra30,
Tegra114, Tegra124.  Here again, the tegra-common directory is needed
to contain commonly-used files.

Tegra directories have been sprinkled in the directory structure.

  arch/arm/cpu/arm720t/tegra20
  arch/arm/cpu/arm720t/tegra30
  arch/arm/cpu/arm720t/tegra114
  arch/arm/cpu/arm720t/tegra124
  arch/arm/cpu/arm720t/tegra-common
  arch/arm/cpu/armv7/tegra20
  arch/arm/cpu/armv7/tegra30
  arch/arm/cpu/armv7/tegra114
  arch/arm/cpu/armv7/tegra124
  arch/arm/cpu/armv7/tegra-common
  arch/arm/cpu/tegra20-common
  arch/arm/cpu/tegra30-common
  arch/arm/cpu/tegra114-common
  arch/arm/cpu/tegra124-common
  arch/arm/cpu/tegra-common

As you see, splitting SoC code by the CPU is not going well,
especially for ARM.
Why don't we collect SoC-specific files into a single place?

A good example we can follow is Linux's arch/arm/mach-* structure.

This item was discussed in the following thread:
http://thread.gmane.org/gmane.comp.boot-loaders.u-boot/188548/

Looks like I got some positive responses and we are almost ready to
start this movement.

This commit prepares arch/arm/Makefile for describing machdirs in it.

After this commit, we can move SoC directory to arch/arm/mach-$(SOC)
in simple steps although some cases such as AT91 and Tegra need more
fixes.

What we generally have to do is:

[1] Move files arch/arm/cpu/$(CPU)/$(SOC)/* to arch/arm/mach-$(SOC)/*
[2] Add machine entry into arch/arm/Makefile
[3] Remove "obj-y += $(SOC)" from arch/arm/cpu/$(CPU)/Makefile
[4] Fix the Kconfig file path in arch/arm/Kconfig
[5] Modify MAINTAINERS if necessary
