c2e857b4ca hw/sd/sdcard: Avoid OOB in sd_read_byte() during unexpected CMD switch
For multi-bytes commands, our implementation uses the @data_start
and @data_offset fields to track byte access. We initialize the
command start/offset in buffer once. Malicious guest might abuse
by switching command while staying in the 'transfer' state, switching
command buffer size, and our implementation can access out of buffer
boundary. For example, CMD17 (READ_SINGLE_BLOCK) allows to read up to
512 bytes, and CMD13 (SEND_STATUS) up to 64 bytes. By switching from
CMD17 to CMD13 (see reproducer below), bytes [64-511] are out of the
'status' buffer.

Our implementation return R0 status code for unexpected commands.
Such in-transaction command switch is unexpected and returns R0.
This is a good place to reset the start/offset fields to avoid
malicious accesses.

Can be reproduced running:

Block Size Register bits [14:12] is SDMA Buffer Boundary, it is missed
in register write, but it is needed in SDMA transfer. e.g. it will be
used in sdhci_sdma_transfer_multi_blocks to calculate boundary_ variables.

Missing this field will cause wrong operation for different SDMA Buffer

3b83079015 hw/sd/sdhci: Do not force sdhci_mmio_*_ops onto all SD controllers
Since commit c0a55a0c9d "hw/sd/sdhci: Support big endian SD host controller
interfaces" sdhci_common_realize() forces all SD card controllers to use either
sdhci_mmio_le_ops or sdhci_mmio_be_ops, depending on the "endianness" property.
However, there are device models which use different MMIO ops: TYPE_IMX_USDHC
uses usdhc_mmio_ops and TYPE_S3C_SDHCI uses sdhci_s3c_mmio_ops.

Forcing sdhci_mmio_le_ops breaks SD card handling on the "sabrelite" board, for
example. Fix this by defaulting the io_ops to little endian and switch to big
endian in sdhci_common_realize() only if there is a matchig big endian variant
available.

interfaces")

22c81783c9 hw/sd/allwinner-sdhost: Don't send non-boolean IRQ line levels
QEMU allows qemu_irq lines to transfer arbitrary integers.  However
the convention is that for a simple IRQ line the values transferred
are always 0 and 1.  The A10 SD controller device instead assumes a
0-vs-non-0 convention, which happens to work with the interrupt
controller it is wired up to.

Coerce the value to boolean to follow our usual convention.

3e20d90824 hw/sd/allwinner-sdhost: Correctly byteswap descriptor fields
In allwinner_sdhost_process_desc() we just read directly from
guest memory into a host TransferDescriptor struct and back.
This only works on little-endian hosts. Abstract the reading
and writing of descriptors into functions that handle the
byte-swapping so that TransferDescriptor structs as seen by
the rest of the code are always in host-order.

This fixes a failure of one of the avocado tests on s390.

c0a55a0c9d hw/sd/sdhci: Support big endian SD host controller interfaces
Some SDHCI IP can be synthetized in various endianness:
https://github.com/u-boot/u-boot/blob/v2021.04/doc/README.fsl-esdhc

 - CONFIG_SYS_FSL_ESDHC_BE

   ESDHC IP is in big-endian mode. Accessing ESDHC registers can be
   determined by ESDHC IP's endian mode or processor's endian mode.

Our current implementation is little-endian. In order to support
big endianness:

- Rename current MemoryRegionOps as sdhci_mmio_le_ops ('le')
- Add an 'endianness' property to SDHCIState (default little endian)
- Set the 'io_ops' field in realize() after checking the property
- Add the sdhci_mmio_be_ops (big-endian) MemoryRegionOps.

93e2da36ed hw/sd: Fix sun4i allwinner-sdhost for U-Boot
Trying to run U-Boot for Cubieboard (Allwinner A10) fails because it cannot
access SD card. The problem is that FIFO register in current
allwinner-sdhost implementation is at the address corresponding to
Allwinner H3, but not A10.
Linux kernel is not affected since Linux driver uses DMA access and does
not use FIFO register for reading/writing.

This patch adds new class parameter `is_sun4i` and based on that
parameter uses register at offset 0x100 either as FIFO register (if
sun4i) or as threshold register (if not sun4i; in this case register at
0x200 is FIFO register).

Tested with U-Boot and Linux kernel image built for Cubieboard and
OrangePi PC.
