that mkimage fails with:

If a unit in a device-tree has an address, a reg property must be provided.
But adding a reg property is not the solution here.

ppc: qemu: Support non-identity PCI bus address

When QEMU originally supported the ppce500 machine back in Jan 2014,
it was created with a 1:1 mapping of PCI bus address. Things seemed
to change rapidly that in Nov 2014 with the following QEMU commits:

commit e6b4e5f4795b ("PPC: e500: Move CCSR and MMIO space to upper end of address space")

and

commit cb3778a0455a ("PPC: e500 pci host: Add support for ATMUs")

the PCI memory and IO physical address were moved to beyond 4 GiB,
but PCI bus address remained below 4 GiB, hence a non-identity
mapping was created. Unfortunately corresponding U-Boot updates
were missed along with the QEMU changes and the U-Boot QEMU ppce500
PCI support has been broken since then.

This commit makes the PCI (non-DM version) work again.

Simon Glass [Thu, 4 Feb 2021 04:29:43 +0000 (21:29 -0700)]
dm: core: Fix allocation of empty of-platdata

With of-platdata we always have a dtv struct that holds the platform data
provided by the driver_info record. However, this struct can be empty if
there are no actual devicetree properties provided.

The upshot of empty platform data is that it will end up as a zero-size
member in the BSS section, which is fine. But if the driver specifies
plat_auto then it expects the correct amount of space to be allocated.

At present this does not happen, since device_bind() assumes that the
platform-data size will always be >0. As a result we end up not
allocating the space and just use the BSS region, overwriting whatever
other contents are present.

Fix this by removing the condition that platform data be non-empty, always
allocating space if requested.

This fixes a strange bug that has been lurking since of-platdata was
implemented. It has likely never been noticed since devices normally have
at least some devicetree properties, BSS is seldom used on SPL, the dtv
structs are normally at the end of bss and the overwriting only happens
if a driver changes its platform data.

It was discovered using sandbox_spl, which exercises more features than
a normal board might, and the critical global_data variable 'gd' happened
to be at the end of BSS.

cannot read it yet (e.g. because U-Boot SW buffer is full) then interrupt
was marked as processed also when HW buffer stayed unprocessed.

U-Boot tried to process this buffer again when it received interrupt again,
but it can receive it only when sender (host) sends a new data. As sender
(host) is not going to send a new data until U-Boot process current data
this issue caused a deadlock in case sender (host) is emitting data faster
than U-Boot can process it.

Reading musb intrrx register automatically clears this register and marks
interrupt as processed. So to prevent marking interrupt in U-Boot as
processed, adds a new variable pending_intrrx which would contain
unprocessed bits of intrrx register.

For a second step, every time when musb_peri_rx_ep() is called and there
are waiting data to be processed (signaled by MUSB_RXCSR_RXPKTRDY) either
acknowledge sender (via musb_peri_rx_ack()) that whole HW buffer was
processed or set corresponding bit in pending_intrrx that HW buffer was not
fully processed yet and next iteration is required after U-Boot allocates
space for reading HW buffer.
