[Qemu-devel] [PATCH v2 0/2] Versatile Express: add modelling of NOR flash

[Qemu-devel] [PATCH v2 0/2] Versatile Express: add modelling of NOR flash

[Francesco Lavra]

This patch series adds modelling of the two NOR flash banks found on the
Versatile Express motherboard. Tested with U-Boot running on an emulated
Versatile Express, with either A9 or A15 CoreTile. The alias of the
first NOR flash in the Cortex-A Series memory map is not modelled.

Changes in v2:
Fix definition of NOR flash 0 address and remove flash alias in Cortex-A
Series memory map.
Use drive_get_next() instead of drive_get() to get a backing storage for
each flash bank.

[Qemu-devel] [PATCH v2 1/2] Versatile Express: Fix NOR flash 0 address and remove flash alias

[Francesco Lavra]

In the A series memory map (implemented in the Cortex A15 CoreTile), the
first NOR flash bank (flash 0) is mapped to address 0x08000000, while
address 0x00000000 can be configured as alias to either the first or the
second flash bank. This patch fixes the definition of flash 0 address,
and for simplicity removes the alias definition.

Something in your email send path is wrapping long lines, which
means 'git am' doesn't work cleanly. If you're planning on sending
more QEMU patches you might want to look into getting this fixed.

Shouldn't these errors be fatal?

Otherwise looks OK.

Oops, sorry about that, if you want me to re-send the patch with these
artifacts fixed, just let me know.

I checked the existing uses of pflash_cfi_0[1,2]_register() in the code,
and if I'm not mistaken only in 5 out of 19 devices these errors are
fatal, in the other 14 cases initialization continues even after flash
registration failure, with or without an error message. Let me know if
you still prefer these errors to be fatal.

So the only reason this can fail is if the user specified a file
to back the flash but trying to read it failed (ie, bad filename
or file not the same size as the flash). I think that merits
actually stopping on error.

Ideally in the long term the flash devices should be converted
to proper QOM devices and we could push the error handling back
into the device itself (which is better positioned to distinguish
"bad filename" from "wrong length" I suspect).

Ok, I will make these errors fatal in v3.

[Qemu-devel] [PATCH v3 0/2] Versatile Express: Add modelling of NOR flash

[Francesco Lavra]

This patch series adds modelling of the two NOR flash banks found on the
Versatile Express motherboard. Tested with U-Boot running on an emulated
Versatile Express, with either A9 or A15 CoreTile. The alias of the
first NOR flash in the Cortex-A Series memory map is not modelled.

Changes in v3:
- When registering either flash bank as CFI device results in an error,
terminate QEMU.

Changes in v2:
- Fix definition of NOR flash 0 address and remove flash alias in
Cortex-A Series memory map.
- Use drive_get_next() instead of drive_get() to get a backing storage
for each flash bank.

[Qemu-devel] [PATCH v2 1/2] Versatile Express: Fix NOR flash 0 address and remove flash alias

[Francesco Lavra]

In the A series memory map (implemented in the Cortex A15 CoreTile), the
first NOR flash bank (flash 0) is mapped to address 0x08000000, while
address 0x00000000 can be configured as alias to either the first or the
second flash bank. This patch fixes the definition of flash 0 address,
and for simplicity removes the alias definition.
