qaudspi spi-nand flash device tree for tf-a and u-boot
Hi, Everybody!
Could anyone help with correct device tree for qspi-nand flash. I can't see any activity on pins connected to flash. If I try to boot from spi-nand with BOOT0..2 set to 1, I can see clear SPI transactions... So, flash connection looks correct.
Flash type is MT29F1G01ABAFDWB
Connected to following pins:
PF10 - CLK
PB6 - NCS
PF8 - IO0
PF9 - IO1
PF7 - IO2
PF6 - IO3
TF-a device tree:
pinctrl node:
qspi_bk1_pins_a: qspi-bk1-0 {

pinmux = <STM32_PINMUX('F', 8, AF10)>, /* QSPI_BK1_IO0 */
<STM32_PINMUX('F', 9, AF10)>, /* QSPI_BK1_IO1 */
<STM32_PINMUX('F', 7, AF9)>, /* QSPI_BK1_IO2 */
<STM32_PINMUX('F', 6, AF9)>; /* QSPI_BK1_IO3 */
bias-disable;
drive-push-pull;
slew-rate = <1>;
};
pins2 {
pinmux = <STM32_PINMUX('B', 6, AF10)>; /* QSPI_BK1_NCS */
bias-pull-up;
drive-push-pull;
slew-rate = <1>;
};
};
qspi_clk_pins_a: qspi-clk-0 {
