[PATCH] ARM: dts: at91: sama7g5ek: Align the impedance of the QSPI0's HSIO and PCB lines
by Tudor Ambarus 27 Apr '22

27 Apr '22

The impedance of the QSPI PCB lines on the sama7g5ek is 50 Ohms. Align the output impedance of the QSPI0 HSIOs by setting a medium drive strength which corresponds to an impedance of 56 Ohms when VDD is in the 3.0V - 3.6V range. The high drive strength setting corresponds to an output impedance of 42 Ohms on the QSPI0 HSIOs. This is just a fine tunning. The memory that we have populated on sama7g5ek works fine even with high drive strength, but it's better to adjust it and use medium instead, in case some other flashes with higher frequencies are tested.

[PATCH 1/2] timers: atmel_tcb: introduce CONFIG_SPL_ATMEL_TCB

This commit allows the ATMEL_TCB driver to be unselected in SPL and be selected in u-boot proper. The SPL can use a different timer. By having a separate Kconfig for ATMEL_TCB in SPL, the size of the SPL decreases by 1 KByte.

[PATCHv3 0/3] Add support for sam9x60_curiosity
by Durai Manickam KR 27 Apr '22

--- v2 -> v3: - Few symbols defined in the board specific header file (i.e) sam9x60_curiosity.h are no longer accepted by the u-boot mainline. So the below changes has been done. - NAND symbols are no longer accepted by the u-boot mainline. This shall be migrated to device tree model. So, this patch series contains only SDMMC support. NAND support will be added once device tree model is implemented. - Removed sam9x60_curiosity_nand_hw_init function from the board specific C file. - Removed the NAND config support in the SDMMC defconfig. - Converted CONFIG_BOOTP_BOOTFILESIZE to Kconfig --- v1 -> v2: - This patch series adds support for sam9x60_curiosity. - Converted CONFIG_ATMEL_LEGACY to Kconfig.
