imx: imx7d-sdb: Add DM QSPI support On iMX7D SabreSD board, the QSPI has pins conflict with EPDC (default). To use QSPI, users have to rework the board (de-populate R388-R391, R396-R399 populate R392-R395, R299, R300). So we add new DTS file and new defconfig dedicated for QSPI. Other changes to support the DM QSPI: - Add QSPI node and alias spi0. - Modify spi4 (spi-gpio) node and add alias spi5 for it to avoid req conflict - Add EPDC node in imx7d.dtsi and disable it in imx7d-sdb-qspi.dts to align with kernel and also present the conflict. - Add -u-boot.dtsi to modify compatible string of mx25l51245g@0 to "spi-flash" - Remove iomux settings of qspi in board codes which is not needed for DM driver.

imx7: Disable CAAM Job Ring 0 Trying to boot a fitImage after a successful hab_auth_img operation causes the following error: ## Loading kernel from FIT Image at 88000000 ...

The reason for this error is that the BootROM uses the CAAM Job Ring 0, so disable its node in U-Boot to avoid the resource conflict. imx8m dtsi files also have the Job Ring 0 disable since the following kernel commit: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/arch?h=v6.5&id=dc9c1ceb555ff661e6fc1081434600771f29657c For a temporary solution, disable the Job Ring 0 in imx7s-u-boot.dtsi.

imx: imx7d-sdb: prepare to synchronise device trees with linux As a preparatory step remove the epdc reference which does not exist in the Linux upstream device tree and rename the qspi1 reference to qspi as this is how it is named in the Linux upstream device tree. This avoids the following error once synchronised: +Error: arch/arm/dts/.imx7d-sdb-qspi.dtb.pre.tmp:10.1-6 Label or path epdc not found +Error: arch/arm/dts/.imx7d-sdb-qspi.dtb.pre.tmp:29.1-7 Label or path qspi1 not found +Error: arch/arm/dts/imx7d-sdb-qspi-u-boot.dtsi:6.1-7 Label or path qspi1 not found Signed-off-by: Marcel Ziswiler <marcel.ziswiler@toradex.com> 2022-07-21 13:27:33 +00:00			`&qspi {`

dts: switch spi-flash to jedec, spi-nor compatible There is no reason not to use the Linux "jedec,spi-nor" binding in U-Boot dts files. This compatible has been added in sf_probe, let use it. This patch switches to jedec,spi-nor when spi-flash is used in the DTS and DTSI files, and removed spi-flash when jedec,spi-nor is already present. The x86 dts are switched in a separate commit since it depends on a change in fdtdec.
