To: u-boot
This is a combined series of the fixes to SH2/SH3/SH4/SH4A architecture port
of U-boot on top of the master branch, there is no functional difference
between this series and 3 my series sent in August 2016 for 2016.09, however
due to many positive generalization updates to U-boot sources the old
unreviewed series can not be cleanly applied anymore:
* [PATCH 0/6] sh4: fix and simplify cache manipulation
* [PATCH 0/5] sh4: fixes to SH7751 PCI host controller
* [PATCH] common: sh: add necessary define bits to board_f
* [PATCH 00/12] sh: change arch and boards code to generic board
I have to resend the changes, because apparently Nobuhiro Iwamatsu is
too busy to maintain SH port and I ask Tom/Simon/Marek and other active
U-boot developers to review and apply the changes, it is highly desirable
to have a possibility to run modern U-boot on boards powered by SH cores.
The changeset implements initial support of relocatable U-Boot code
for SH2/SH3/SH4 architectures and boards, as weel as it restores
a possibility to boot U-Boot on SH boards, which has not been converted
to generic board in time (for more details see commit f41e6088eb1
("sh: Fix build errors for generic board")). Special attention from
maintainers of all touched boards is required, due to inaccessibility
of hardware for me it would be a troublesome task.
*** CACHE SUPPORT COVER LETTER ***
In my tests I experience that sometimes SH4 does not properly
fetch instructions after immediate jump to a code loaded by
means of rtl8139, the problem is gone if "icache off" is
executed after load or if cache invalidation and write-back
is used on data load instead of just cache invalidation,
which is apparently an improper backbone of flush_dcache_range()
function.
The changeset contains a couple of bugfixes and a general
simplification of the code related to cache manipulation. Note
that while caches are found on SH2 and SH3 for long time
they were inactive in U-Boot, because I don't have SH2/SH3
hardware for testing I don't spread SH4 cache fixes to those
cpus, however generally it should be the same, in that case
arch/sh/cpu/sh4/cache.c file can be moved to arch/sh/lib
folder
*** PCI CONTROLLER CHANGES COVER LETTER ***
This series fixes 2 bugs found in SH7751 PCI host controller driver,
also it restores r2dplus defconfig and slightly simplifies the code
related to the SH7751 PCI controller, more improvements may follow
in future.
The change is independent on the following conversion to generic
board, however it adds some bits to simplify porting of r2dplus
board by moving board specific CONFIG_SYS_TEXT_BASE into P1 area,
Before the change even if rtl8139 driver is selected in a defconfig
the device was unusable due to invalid phys to bus mapping (e.g. test
with 'dhcp' command shows it), this most probably was caused by some
unnoticed generic change in PCI driver framework, however now it is
fixed by the series.
*** GENERIC BOARD CHANGES COVER LETTER ***
Now code/data initialization and relocation in general resemble the
procedure on ARM with minor peculiarities (same one relocation from a
storage device if calculated reloc_off == 0, otherwise two relocations),
however please note that the change does *not* add PIE support (only PIC),
so it may end up that there are persistent pointers to some non-relocated
data, this point requires better investion.
Only r2dplus board is actually converted to support new architectural
changes, the rest of the boards require attention from board maintainers
or they will be removed. Board maintainers may pay attention to
CONFIG_SYS_MALLOC_CLEAR_ON_INIT, CONFIG_NEEDS_MANUAL_RELOC,
CONFIG_SYS_GENERIC_GLOBAL_DATA etc. options.
This r2dplus board change allows immediately check the correctness of
the series on a r2dplus qemu target, note that the second copy is
not avoided in this case, also for simplicity SDRAM area up to text base
is large enough to store malloc pool and two copies of loaded code/data.
The change was tested on one custom SH4 (SH7551R) board, r2dplus qemu
target (see also SH7751 PCI change under review), the rest of the boards
are compile tested only.
Multiple kudos to Simon for great patience and a decision to not remove
the code.

In common usecases flush_cache() assumes both cache invalidation and
write-back to memory, thus in flush_dcache_range() implementation
change SH4 cache write-back only instruction 'ocbwb' with cache purge
instruction 'ocbp', according to the User's Manual there should be no
performance penalty for that.
Note that under circumstances only cache invalidation is expected from
flush_cache() call, in these occasional cases the current version of
flush_cache() works, which is a wrapper over invalidate_dcache_range()
at the moment, this will be fixed in the following change.

In common usecases flush_cache() assumes both cache invalidation and
write-back to memory, instead of doing cache invalidation only with
the wrapped 'ocbi' instruction pin flush_cache() to cache invalidation
with memory write-back done by 'ocbp'.

The change is similar to commit 994b56616bae ("sh: delete an unused
source file") for SH2, however here the removed cache.c file was
built and included into an image as a dead code.
If it is needed in future the contents can be reused from a similar
arch/sh/cpu/sh4/cache.c file, which is in turn will be moved to
a shared among all core flavours location at arch/sh/lib/cache.c.

Both jump_to_P2() and back_to_P1() functions are found in asm/system.h
header file and functionally they are the same, don't redefine them.

cache_wback_all() is a local function and it is called from
cache_control() only, which is in turn jumps to P2 area.
The change fixes an issue when cache_wback_all() returns from P2 to
P1, however cache_control() continues to manipulate with CCR
register, according to the User's Manual this is restricted.

No functional change, moving cache manipulation functions into cache.c
allows to collect all of them in a single location and as a pleasant
side effect cache_control() function can be unexported now.

The change actually maps PCI I/O window to the same address on PCI bus
as it is stated by a comment, before the change transfers to the PCI I/O
space are failed due to misconfiguration of the most significant 14 bits
of the PCI address in PCIIOBR (note that it is set to 0x0).
Most probably the problem remained unnoticed, because communcation
to all tested PCI devices is done over PCI memory space only.

For ease of use and accounting a condition that on SH4
pci_phys_to_bus() and pci_bus_to_phys() are one in one mappings due to
unimplemented __iomem() conversion, this change fixes access to SDRAM
memory by PCI devices.
This change also generalizes PCI system memory configuration, which is
taken from board specific defines rather than hardcoded in the PCI
host driver.

While both options are acceptable use P1 area physical addresses
instead of external memory space of text base and PCI system memory
for unification purposes, all other supported superh boards have the
same selection.
This allows to easily ensure that CONFIG_SYS_TEXT_BASE is located
within available DRAM.

CONFIG_RTL8139 was moved to a board defconfig by a commit 86e9dc86b1a2
("net: Move CONFIG_RTL8139 to Kconfig"), however it was done
incorrectly due to a missing CONFIG_NETDEVICES selection, thus
virtually it was just a removal of the driver compilation.
As an unlucky consequence the option was completely removed by a purge
commit adad96e60d0e ("configs: Re-sync HUSH options"), restore the
driver inclusion back.

Since a platform conversion to generic board support has not been
accomplished some architecture specific bits are missing from board_f
init sequence, the change adds a number of basic expected callbacks
into early init sequence.

From: Vladimir Zapolskiy @ 2016-11-27 22:15 UTC (permalink / raw)
To: u-boot
Three supported SH4/SH4A boards with the bootloader image stored on
SPI flash have own flavour of a linker script, in turn they are equal
among each other. The only difference is that the text from
lowlevel_init.o is placed right after start.o, which makes sense.
Note that .bss section is not marked as NOLOAD, because for about
10 years this is a default option of a GNU linker, either the
attribute is found or not the resulting image file is the same.

No functional change, concentrate linker script commands in one
place for convenience. Entry point is set to CONFIG_SYS_TEXT_BASE by
default on build, so this option can be omitted from being added to
the linker script.

At the moment in runtime all defined sections are copied into or
created in RAM, specify this explicitly to assert potential out of RAM
placements of the sections.

By default this undef is a noop, moreover at this point when the
platform support is broken is prevents debugging of U-boot by manual
insertion of #define DEBUG into common files, so it makes sense to
remove the option from all SH boards as a harmful one.

All SH boards define a checkboard() function which outputs basic board
information on boot, however generic board support requires to define
CONFIG_DISPLAY_BOARDINFO to do that, so define it for the boards.

From: Vladimir Zapolskiy @ 2016-11-27 22:15 UTC (permalink / raw)
To: u-boot
Generic board support assumes a different method of specifying
DRAM size on board, also it can be shared among all boards, notably
only sh7763rdp board has a custom legacy dram_init(), however
the difference is only in printing some additional information,
this feature can be removed.

Commits b61e90e6fd83 ("sh: Drop the arch-specific board init") and
f41e6088eb1a ("sh: Fix build errors for generic board") left code and
data relocation done in start.S, however further actual U-boot
configuration is not started anymore. Practically SH boards with the
code relocated into the expected position by start.S still can be
booted, so the change adds this option and provides an option how to
relocate code for board_init_r() execution.

Like on ARM platform keep the first code relocation from a U-boot
image storage to RAM at CONFIG_SYS_TEXT_BASE, then pass execution to a
generic board_init_f() with empty GD flags. If CONFIG_SYS_TEXT_BASE is
equal to a calculated by board_init_f() relocation address there will
be no more code and data copy, however it's worth to mention that the
first copy happens even if $pc on _start is the same as
CONFIG_SYS_TEXT_BASE, on practice this works without a problem.
Also note that _sh_start is renamed back to _start to correct
gd->mon_len calculation by setup_mon_len(), the opposite rename was
done in pre-generic board commit 2024b968ee9 ("sh: Fix build in start.S").

It is easy to note that SH2/SH3/SH4 start.S code is practically
the same with a minor difference for SH2 where a short data header is
present. To avoid unwanted code duplication and to automatically
convert SH2 and SH3 platforms to generic board support move fixed SH4
start.S into arch/sh/lib/start.S and share it among all platforms.

Finally add fpic compilation option to produce relocatable code.
Note that this requires to define CONFIG_NEEDS_MANUAL_RELOC for all
board files, also relocation support still has some limitations
(e.g. a developer should care not to overwrite the executing code or
memset() with zeroes not yet relocated data on malloc init etc.),
which may be fixed while switching to PIE.
Due to short investigation the architecture code is not ready for PIE
linking, this will require some manipulations with .dyn* sections.

This change allows to reserve enough space at the end of board SDRAM
to store two copies of U-Boot and malloc heap.
Due to selection of the CONFIG_SYS_TEXT_BASE the second code/data
copying is not avoided, first of all this may depend on a used
toolchain, secondly at this point some level of volatility is wanted
to do more platform changes and do not care about probably changed
calculated in runtime relocation offset.

clearly Renesas abandoned SH architecture as a legacy one (and probably
as a competing with R-Car one), but until J4 core as a replacement for
Renesas SH4 is released by j-core.org project it is desirable to keep
U-Boot running on SH platforms.
I'm interested in maintainership of SH and thereafter J-Core cores, but
practically I have only one SH4 powered board on hand, unfortunately
begging for hardware donations was not so successful. At the moment
U-Boot contains SH2A/SH3/SH4/SH4A arch support and boards, I have to
figure out where to get more boards to cover more SoC flavours, and
getting legacy hardware is always a problem, because it is not on
a store's shelf.
To start from I would recommend to decouple u-boot-sh.git fork into
independent SH and ARM R-Car repositories, the latter one will be
maintained by Renesas associates.

The displayed qemu output is expected and can be ignored, currently SH
port in qemu is in "odd fixes" maintainership stage, hopefully I'll
find time to send a patch to silence this.

I use this list of components to build and test U-Boot on r2dplus
qemu target and SH7751 powered board I have on hand (it is quite
similar to r2dplus devkit):
* SH4 toolchain from buildroot distro with musl (libc flavour most
probably is unrelated to U-boot or kernel):
- gcc-5.3.0
- musl-1.1.12
- linux-4.4 headers
* qemu-system-sh4 is from standard Debian qemu-system-misc package:
- qemu-system-misc-1:2.6+dfsg-3
- qemu-2.6.50 vanilla build also works for me fine
* U-Boot compilation:
% make ARCH=sh CROSS_COMPILE=sh4-buildroot-linux-musl-
CC='sh4-buildroot-linux-musl-gcc -Wall' r2dplus_defconfig
% make ARCH=sh CROSS_COMPILE=sh4-buildroot-linux-musl-
CC='sh4-buildroot-linux-musl-gcc -Wall' u-boot.bin
Command to run qemu with output directly to a console is similar to
the command you mentioned above (press Ctrl-C to terminate):
% qemu-system-sh4 -M r2d -kernel u-boot.bin -monitor null -serial null
-serial stdio -nographic
This is an example of testing on my end (omitting "long write ..
ignored" messages):

I'm interesting in having J-Core work and be maintained in U-Boot, so
lets make this work. With regards to legacy platforms, I'm happy to
drop things which are unavailable / non-functional and just note in
doc/README.scrapyard when things were removed. We did this a lot around
a year ago and probably should again.
And then yes, the R-Car patches should come in via another repository
rather than u-boot.sh as was previously convenient.

Ah, OK. With that exact command line I can get things going. My gut
feeling, having played with other qemu boards as a user, is that there's
something odd going on in how qemu is parsing the arguments and
assigning things as the defaults "should" provide this too, but instead
we're disabling the defaults for monitor and serial (which can usually
be multiplexed) and then only giving serial to stdio.
But, the good news is that this means I can get travis-ci going and make
add r2dplus to the list of tested-every-time platforms. I'll follow up
to your series with patches for that hopefully tomorrow.
