The iMX lpuart driver added at 44e17aa60d47 ("xen/arm: Add i.MX lpuart driver")
is not enough to boot a Linux based dom0 when certain drivers, such as the
watchdog driver, are enabled.We're also fixing compatibles in imx-lpuart to allow Xen to use the UART on the QXP variant as well. NOTE: There's still an open point regarding the watchdog from v1, but I wanted to post this series to show the filtering changes mostly because they also clarify what exists and what we can definitely get away with blocking / ignoring out of all the SMC SIP calls. v2: (See each path for complete changelog) - Added SIP call filtering (Julien Grall) - Replace lpuart compatible instead (Julien Grall) v1: https://lore.kernel.org/xen-devel/20240131114952.305805-1-john.ernb...@actia.se John Ernberg (2): xen/arm: Add imx8q{m,x} platform glue xen/drivers: imx-lpuart: Replace iMX8QM compatible with iMX8QXP xen/arch/arm/platforms/Makefile | 1 + xen/arch/arm/platforms/imx8qm.c | 143 ++++++++++++++++++++++++++++++++ xen/drivers/char/imx-lpuart.c | 2 +- 3 files changed, 145 insertions(+), 1 deletion(-) create mode 100644 xen/arch/arm/platforms/imx8qm.c -- 2.43.0
