Royyan Zahir f7f8107a0a arch/arm64/imx9: add an ELE-backed /dev/random driver. ... The i.MX9 has a true random number generator behind the EdgeLock Enclave and imx9_ele_get_random() to reach it, but nothing registers a character device for it, so the entropy pool is never seeded from hardware. stm32h7, nrf52, lpc54xx and rp23xx all provide one; imx9 does not. imx9_ele.c was built only for CONFIG_IMX9_BOOTLOADER, putting the enclave out of reach of the application core. It moves behind a new CONFIG_IMX9_ELE that the bootloader selects, so existing configurations build as before. A transfer that never lands is silent, so the buffer is prefilled with a pattern and a block still holding it is refused, as is an all-zero block and, by the FIPS 140-2 continuous test, a repeat of the one before. Compiles for imx93-evk:nsh with CONFIG_IMX9_RNG=y. Signed-off-by: Royyan Zahir <royzah@gmail.com>		2026-09-27 11:02:13 -03:00
