This patch series restores minimal U-Boot support for
the ST-Ericsson NovaThor U8500 SoC.
Previous support for U8500 was removed in
commit 68282f55b846 ("arm: Remove unused ST-Ericsson u8500 arch")
since none of the boards were converted to generic boards
before the deadline.
The motivation for adding the SoC and board is explained in
- Patch 3 ("arm: Add support for ST-Ericsson U8500 SoC") and
- Patch 5 ("board: Add new Samsung "stemmy" board based on ST-Ericsson U8500")
I have additional patches for MMC, USB, display and the "stemmy"
board, that configure it to provide an Android fastboot interface
with similar functionality as the original Samsung bootloader.
Some of the patches require some additional work, so I thought
it is easier to start with some minimal changes first (only UART).
I think this makes the patch series quite straightforward,
with only ~225 new lines of C code, plus device tree and documentation.
The only patch that stands out with ~1.8k lines is the device tree
import, directly copied (without modification) from the Linux kernel.

The Nomadik Multi Timer Unit (MTU) provides 4 decrementing
free-running timers. It is used in ST-Ericsson Ux500 SoCs.
The driver uses the first timer to implement UCLASS_TIMER.

I ignored all the checkpatch complaints in this patch,
since the files are copied without modification from the Linux kernel.
I will check if it makes sense to submit a patch to fix some of them...
(In particular the large amount of "WARNING: please, no space before tabs"
in one of the includes...)

From: Stephan Gerhold @ 2020-01-04 17:45 UTC (permalink / raw)
To: u-boot
The NovaThor U8500 SoC was released by ST-Ericsson in 2011.
It was used for some development boards like the CALAO Systems
Snowball SBC, but mass production was primarily for Android
smartphones like the Samsung Galaxy S III mini.
Previous support for U8500 was removed in
commit 68282f55b846 ("arm: Remove unused ST-Ericsson u8500 arch")
since none of the boards were converted to generic boards
before the deadline.
The new code does not have much in common with the previous code.
I have completely rewritten everything, embracing the Driver Model
and device trees wherever possible.
The U8500 support is a bit more minimal for now - my primary
use case is to use U-Boot as alternative bootloader for some of the
U8500 Samsung smartphones. At the moment U-Boot is chain-loaded from
the original Samsung bootloader. A side effect of this is that we
can (temporarily) get away without implementing some functionality
- e.g. all clocks are already enabled by the original bootloader.
More functionality will be added in future patches.

To: u-boot
The ST-Ericsson U8500 SoC has been used in mass-production for
some Android smartphones released around 2012.
In particular, Samsung has released more than 5 different
smartphones based on U8500, e.g.
- Samsung Galaxy S III mini (GT-I8190) "golden"
- Samsung Galaxy S Advance (GT-I9070) "janice"
- Samsung Galaxy Xcover 2 (GT-S7710) "skomer"
and a few others.
Mainline Linux has great support for the Ux500 SoC, so these
smartphones can also run Linux mainline quite well.
Unfortunately, the original Samsung bootloader used on these devices
has limitations that prevent booting Linux mainline directly.
It keeps the L2 cache enabled, which causes Linux to crash very early,
shortly after decompressing the kernel.
Using U-Boot allows to circumvent these limitations. We can let the
Samsung bootloader chain-load U-Boot and U-Boot locks the L2 cache
before booting into Linux. U-Boot has several other advantages
- it supports device-trees directly and we are no longer limited to
flashing Android boot images through Samsung's proprietary download
mode.
The Samsung "stemmy" board covers all Samsung devices based on U8500.
Add minimal support for "stemmy". For now only UART is supported but
this will be extended later.

+ST-Ericsson U8500 Samsung "stemmy" board
+========================================
+
+The "stemmy" board supports Samsung smartphones released with
+the ST-Ericsson NovaThor U8500 SoC, e.g.
+
+ - Samsung Galaxy S III mini (GT-I8190) "golden"
+ - Samsung Galaxy S Advance (GT-I9070) "janice"
+ - Samsung Galaxy Xcover 2 (GT-S7710) "skomer"
+
+and likely others as well (untested).
+
+At the moment, U-Boot is intended to be chain-loaded from
+the original Samsung bootloader, not replacing it entirely.
+
+Installation
+------------
+
+1. Setup cross compiler, e.g. export CROSS_COMPILE=arm-none-eabi-
+2. make stemmy_defconfig
+3. make
+
+For newer devices (golden and skomer), the U-Boot binary has to be packed into
+an Android boot image. janice boots the raw U-Boot binary from the boot partition.
+
+4. Obtain mkbootimg, e.g. https://android.googlesource.com/platform/system/core/+/refs/tags/android-7.1.2_r37/mkbootimg/mkbootimg
+5. mkbootimg \
+ --kernel=u-boot.bin \
+ --base=0x00000000 \
+ --kernel_offset=0x00100000 \
+ --ramdisk_offset=0x02000000 \
+ --tags_offset=0x00000100 \
+ --output=u-boot.img
+
+6. Enter Samsung download mode (press Power + Home + Volume Down)
+7. Flash U-Boot image to Android boot partition using Heimdall:
+ https://gitlab.com/BenjaminDobell/Heimdall
+
+ heimdall flash --Kernel u-boot.(bin|img)
+
+8. After reboot U-Boot prompt should appear via UART.
+
+UART
+----
+
+UART is available through the micro USB port, similar to the Carkit standard.
+With a ~619kOhm resistor between ID and GND, 1.8V RX/TX is available at D+/D-.
+
+Make sure to connect the UART cable *before* turning on the phone.

Since we are approaching the end of the merge window,
I was wondering if there is anything I can do to get this patch set
applied for v2020.04?

Since you had marked it as RFC, I had marked it as such in patchwork and
overlooked it. I'll take a look soon, thanks.

Thank you! I thought marking it as RFC is appropriate since I'm adding a
new SoC and this is my first U-Boot patch. But it is working fine,
so unless there are comments it should be good to go :)
