Introduce a new sunxi-spl-with-ecc.bin image with already the right header,
ECC, randomizer and padding for the BROM to be able to read it.

It needs to be flashed using a raw access to the NAND so that the

Maxime Ripard [Mon, 27 Feb 2017 17:22:09 +0000 (18:22 +0100)]
mtd: sunxi: Change U-Boot offset

The default U-Boot offset for the Allwinner SoCs was set to 32kB.

This was probably to try to maintain some compatibility with the current
image that we build for the MMC where the U-Boot binary is also located at
a 32kB offset.

However, this causes a number of issues. The first one is that it prevents
us from using a backup SPL entirely, which is troublesome in case where the
first would be corrupt (especially on MLC which have a higher number of
bitflips).

We also cannot use the original MMC image on the NAND, because we need to
prepare the SPL image to include the ECCs and randomizer settings, which
reduces the interest of setting it at that particular offset.

It also prevents us from upgrading and flashing the U-Boot and SPLs
independantly, since it's very likely that it will fall in the same erase
block.

Since that default wasn't used by any board, change it for 8MB, which will
be in an erase block of its own, all the erase blocks being multiple of
two. The highest erase block size we encountered is 4MB, which means that
in this particular setup, the first and second erase blocks will be for the
SPL and its backup, and the third for U-Boot.

nand: sunxi: Fix modulo by zero error

When trying to autodetect the ECC and randomization configurations, the
driver starts with a randomization disabled and no seeds.

In this case, the number of seeds is obviously 0, and the randomize boolean
is set to false.

However, the logic that retrieves the seed for a given page offset will
blindly use the number of seeds, without testing if the randomization is
enabled, basically doing a modulo by 0.

As it turns out, the libgcc in the common toolchain returns 0 here, which
was our expected value in such a case, and why we would not detect it.
However, U-Boot's libgcc will for some reason return from the function
instead, resulting in an error to load the U-Boot binary in the SPL.

This both follows how the BootROM probes devices and is a sane default

easy factory programming of unpersonalised devices using an SD card)
and field usage (with customer devices expected to have their firmware
either in SPI or MMC).

However, when probing multiple interfaces (according to the result
from the board_boot_order function), we need to ensure that only valid
FIT images are considered and disable the fallback to assuming that a
raw (binary-only) U-Boot image is loaded (to avoid hangs/crashes from
jumping to random content loaded from devices that are probed, but
don't contain valid image content).

By disabling the SPL_RAW_IMAGE_SUPPORT and SPL_LEGACY_IMAGE_SUPPORT
options, we ensure that raw images (indistinguishable from random
data) are not considered for booting.

in a Qseven-compatible form-factor.

These changes add a device-tree describing the board and its

This includes the following changes from the original development:

 * dts: rk3399-puma: add gmac for the RK3399-Q7

The SPI5 controller is routed to the Q7 edge connector and provides
general-purpose SPI connectivity for customer base-boards.

With some minor improvements on integration into our outbound tree

then be configured via the 'u-boot,spl-boot-order' property in the
chosen-node of the DTS.

While this approach is easily extensible to other boards, it is only
implemented for the RK3399 for now, as the large SRAM on the RK3399
makes this easy to fit the needed infrastructure into SPL and our
production setup already runs with DM, OF_CONTROL and BLK in SPL.

The new boot-order property is expected to be used in conjunction with
FIT images (and all legacy image formats disabled via Kconfig).

A boot-sequence with probing and fallthroughs from SPI via eMMC to SD

rockchip: spl: RK3399: add COUNTER_FREQUENCY define to rk3399_common.h

The BootROM of the RK3399 SoC does not initialise the cntfrq_el0 (which
holds the value 0 (zero) on entry into the SPL. This causes the timebase
for U-Boot not to advance (and will cause a hang where a timeout would
be expected... e.g. if something goes wrong during MMC/SD card startup).

This change defines COUNTER_FREQUENCY, which is used by the AArch64 init
code in arch/arm/cpu/armv8/start.S to set up cntfrq_el0 (if necessary).

rockchip: video: Split out HDMI controller code

Designware HDMI controller and phy are used in other SoCs as well. Split
out platform independent code.

DW HDMI has 8 bit registers but they can be represented as 32 bit
registers as well. Add support to select access mode.

EDID reading code use reading by blocks which is not supported by other
SoCs in general. Make it more general using byte by byte approach, which
is also used in Linux driver.

Finally, not all DW HDMI controllers are accompanied with DW HDMI phy.
Support custom phys by making controller code independent from phy code.

rockchip: rk3188: Setup the armclk in spl

The armclk starts in slow mode (24MHz) on the rk3188, which results in U-Boot
startup taking a lot of time (U-Boot itself, but also the rc4 decoding done
in the bootrom).

With default pmic settings we can always reach a safe frequency of 600MHz
which is also the frequency the proprietary loader left the armclk at,
without needing access to the systems pmic.

rockchip: clk: rk3188: Allow configuration of the armclk

The armclk starts in slow mode (24MHz) on the rk3188, which makes the whole
startup take a lot of time. We therefore want to at least move to the safe
600MHz value we can use with default pmic settings.
This is also the freqency the proprietary sdram-init leaves the cpu at.

For boards that have pmic control later in u-boot, we also add the option
to set the maximum frequency of 1.6GHz, if they so desire.

rockchip: rk3188: Cleanup some SPL/TPL rename leftovers

In the beginning, we did SPL -> TPL -> U-Boot, but after clarification
of the real ordering swapped SPL and TPL.
It seems some renames were forgotten and may confuse future readers, so
also swap these to reflect the actual ordering.
