riscv: restore global data pointer in trap handler
The gp register is used to store U-Boot's global data pointer. We should
not assume that an UEFI application leaves the gp register unchanged as
the UEFI specifications does not define who is the owner of the gp and tp
registers.
So the following sequence should be followed in the trap handler:
* save the caller's gp register
* restore the global data pointer
* serve interrupts or print crash dump and reset
* restore the caller's gp register

arm64: a37xx: pci: Disable link training when unloading driver
As required by PCI Express spec a delay for at least 100ms after
de-asserting PERST# signal is needed before link training is enabled.
Linux kernels prior to 5.8 version do not automatically disable link
training before de-asserting PERST# signal, therefore this requirement is
not fulfilled.
Above requirement is needed for proper detection of some Compex PCIe WiFi
cards. Otherwise Linux kernel cannot detect it.
To allow using those PCIe cards with older Linux kernel versions booted by
U-Boot compiled with U-Boot a37xx pci driver, disable link training in
U-Boot when unloading this pci driver.
Thanks to DM_FLAG_OS_PREPARE flag, U-Boot automatically unload this driver

The GPIO bank name for banks J and K are not correct when using the
'gpio' command from the console.
The driver derives the bank name from the device tree instance string by
using the instance value and adding 'A': gpio0@xxaddrxx is Bank A,
gpio1@yyaddryy is Bank B and so on.
On the PIC32, there is no Bank I so instances 8 and 9 need to be
incremented as a minimum change.
An alternative (less opaque) implementation would be to use a bank-name
property instead but this would require modifying the driver code too.

GPIO state cannot be changed via the device tree (e.g. with gpio-hog) or
using the 'gpio' command from the console.
The root cause is a discrepancy between the driver and the device tree:
the driver code expects an absolute I/O address in the <reg> property,
while the device tree defines the address relative to a declaration in
the parent pinctrl node.
Changing the device tree to fix a driver issue would normally be wrong,
however:
- I have run the first version of U-Boot in which this driver appears
(v2016.03) and the same problem exists, so this is not a regression;
- There is no code that references a parent device tree node that might
suggest the intent of the author was to parse the DT as it exists now;
- The equivalent Linux PIC32 GPIO driver also uses absolute addresses
for the GPIO <reg> property. This change brings the U-Boot DT more
into line with Linux.
Additionally, the data sheet (Microchip ref. 60001361H) shows that the
register set to control a GPIO bank spans 0xE0 bytes, but the device
tree specified size is only 0x48 bytes.

Somewhere between v2020.04 and v2020.07 the mpc8xxx_spi driver broke,
I'm guessing due to this hunk
@@ -559,6 +560,8 @@ int dm_gpio_set_dir_flags(struct gpio_desc *desc, ulong flags)
if (ret)
return ret;
+ /* combine the requested flags (for IN/OUT) and the descriptor flags */
+ flags |= desc->flags;
ret = _dm_gpio_set_dir_flags(desc, flags);
from commit 695e5fd5469a ("gpio: update dir_flags management"). But
the blame is mostly on the driver itself which seems rather confused:
The chip select gpios are requested with GPIOD_ACTIVE_LOW, but then in
each activate/deactivate, dm_gpio_set_dir_flags() is called with
merely GPIOD_IS_OUT, and then the driver call set_value(0) for
activate.
That used to work, but with the above hunk, the ACTIVE_LOW setting
from the request becomes persistent, so the gpio driver ends up being
asked to set the value to 1 in mpc8xxx_spi_cs_activate().
So drop the dm_gpio_set_dir_flags() calls in the activate/deactivate
functions, and use a value of 1 to mean "logically enabled".
Ideally, I think we should also drop the GPIOD_ACTIVE_LOW from the
request and make it up to the list of gpio cs in DT to indicate
whether that CS is enabled when driven low (as is of course usually
the case), but that requires changing
arch/powerpc/dts/gdsys/gazerbeam-base.dtsi among others, and I don't
have that hardware to test on. I have, however, tested our
own (mpc8309-based) hardware with this change, and I have also tested

The bitflip test uses two equal sized memory buffers. This is achieved
by splitting the range of memory into two pieces. The address of the

This patch fixes the pointer arithmetic problem.
A second problem arises because u-boot "mtest" command expects the
ending address to be inclusive. When computing (end - start) this
results in missing 1 byte of the requested length. The bitflip test
expects a count rather than an "ending" address. Thus it fails to test
the last word of the requested range. Fixed by using (end - start + 1).
Added Kconfig option to optionally disable the bitflip test, since it
does add significantly to the time taken for "mtest".
