[00/14] i.MX and SDHCI improvements

Message

Bernhard Beschow Jan. 8, 2025, 9:25 a.m. UTC

This series fixes some details in i.MX platform devices, improves SDHCI
compatibility with U-Boot and modernizes some code.

The first 6 patches are bugfixes 1/ resolving infinite loop in U-Boot esdhc
driver, 2/ fixing a character echoing issue in imx-serial, 3/ fixing IRQ sharing
issue in Designware PCIe emulation, and 4/ fixing GPIO level preservation across
resets in imx-gpio. The IRQ sharing issue is fixed using a new device type
"TYPE_SHARED_IRQ" which is inspired by TYPE_SPLIT_IRQ.

Patches 7 and 8 modernize SD card emulation by turning presence and
write-protect GPIOs into qdev GPIOs and then further allowing the GPIOs to be
inverted, just like device tree allows.

The rest of the series is cosmetics including turning DPRINTF() into trace
events which eases debugging.
