From: Frieder Schrempf <frieder.schrempf@kontron.de>
These SoMs and boards are developed and sold by Kontron Electronics
GmbH. All basic peripherals for booting are supported.
Patches 1 to 4 are for preparation. Patch 5 adds support for the
i.MX6UL/ULL boards and patch 6 for the i.MX8MM boards.
Frieder Schrempf (6):
mtd: spi-nor-ids: Add support for Macronix MX25V8035F and MX25R1635F
spi: fsl_qspi: Build driver only if DM_SPI is available
clk: imx8mm: Add SPI clocks
imx8m: Restrict usable memory to space below 4G boundary
imx: imx6ul: Add support for Kontron Electronics SL/BL i.MX6UL/ULL
boards (N63xx/N64xx)
imx: imx8mm: Add support for Kontron Electronics SL/BL i.MX8M-Mini
boards (N801x)

The MX25V8035F is a 8Mb SPI NOR flash and the MX25R1635F is very
similar, but has twice the size (16Mb) and supports a wider supply
voltage range.
They were tested on the Kontron Electronics i.MX6UL and i.MX8MM SoMs.

The driver depends on DM_SPI and if it's not available (e. g. in SPL),
then we should not try to build it as this will fail.

Some IPs have their accessible address space restricted by the
interconnect. Let's make sure U-Boot only ever uses the space below
the 4G address boundary (which is 3GiB big), even when the effective
available memory is bigger.
We implement board_get_usable_ram_top() for all i.MX8M SoCs, as the
whole family is affected by this.

This adds support for i.MX6UL/ULL-based evaluation kits with SoMs by
Kontron Electronics GmbH.
Currently there are the following SoM flavors (SoM-Line):
* N6310: SOM with i.MX6UL-2, 256MB RAM, 256MB SPI NAND
* N6311: SOM with i.MX6UL-2, 512MB RAM, 512MB SPI NAND
* N6411: SOM with i.MX6ULL, 512MB RAM, 512MB SPI NAND
And the according evaluation boards (Board-Line):
* N6310-S: Baseboard with SOM N6310, eMMC, display (optional), ...
* N6311-S: Baseboard with SOM N6311, eMMC, display (optional), ...
* N6411-S: Baseboard with SOM N6411, eMMC, display (optional), ...
Currently U-Boot describes i.MX6UL and i.MX6ULL through separate config
options at compile-time. Though the differences are so minor, that for
the scope of these SoMs we just use a single defconfig that is compatible
with both SoCs.

From: Frieder Schrempf <frieder.schrempf@kontron.de>
The Kontron SoM-Line i.MX8MM (N801x) by Kontron Electronics GmbH is a SoM
module with an i.MX8M-Mini SoC, 1/2/4 GB LPDDR4 RAM, SPI NOR, eMMC and PMIC.
The matching evaluation boards (Board-Line) have 2 Ethernets, USB 2.0, HDMI/LVDS,
SD card, CAN, RS485 and much more.

Just for the note: this codestyle is controversy. At the beginning, C++
comments were rejected in code. However, I see al ot of new code (not
only imported by other sources like kernel or something else) has
introduced in U-Boot C++ comments, and it makes no sense I complain here
when in other parts were accepted. If nobody complains, I am fine with
C++ comments, too.

That could cause extra mem copy. Bounce buffer would be good for systems
that take U-Boot as UEFI firmware, because U-Boot would be located at
high end, but in the middle just top of 4GB.
I not object this patch, but it also be good if bounce buffer be added
for improvement.

If you want to avoid the extra memcopy, then make sure the buffers are
not allocated above 4 GiB boundary. Then the bounce buffer does no copy.
This board_get_usable_ram_top() is just a temporary workaround for
platforms with broken drivers which are not fixed yet, so please fix the
drivers instead.

The bounce buffer is a necessity for IPs which cannot address more than
the 4 GiB of memory. In fact, it would be even better to handle DT
dma-ranges, but that is the next step.

I do object to this, since it increases the proliferation of this broken
board_get_usable_ram_top() workaround instead of fixing the drivers
properly.

I generally agree with Marek's objections and if anyone comes up with a proper fix this will be highly appreciated. For now I just dropped this patch from my v2 patchset, but Stefano has already pulled it into u-boot-imx. I guess it's up to him to decide if this intermediate fix should be merged or not.

Fix the drivers, that is the only way unless you want to see U-Boot turn
into pile of hacks and workarounds which become unmanageable.
