Luca Ceresoli [Mon, 4 Jun 2018 10:21:01 +0000 (12:21 +0200)]
arm64: zynqmp: accept an absolute path for PMUFW_INIT_FILE

The value of PMUFW_INIT_FILE is prefixed with "$(srctree)/", thus
forcing it to be a relative path inside the U-Boot source tree. Since
the PMUFW is a binary file generated outside of U-Boot, the PMUFW
binary must be copied inside the U-Boot source tree before the
build.

This generates a few problems:

 * if the source tree is shared among different out-of-tree builds,
   they will pollute (and potentially corrupt) each other
 * the source tree cannot be read-only
 * any buildsystem must add a command to copy the PMUFW binary
 * putting an externally-generated binary in the source tree is ugly
   as hell

Avoid these problems by accepting an absolute path for
PMUFW_INIT_FILE. This would be as simple as removing the "$(srctree)/"
prefix, but in order to keep backward compatibility we rather use the
shell and readlink to get the absolute path even when starting from a
relative path.

Since 'readlink -f' produces an empty string if the file does not
exist, we also add a check to ensure the file configured in
PMUFW_INIT_FILE exists. Otherwise the build would exit successfully,
but produce a boot.bin without PMUFW as if PMUFW_INIT_FILE were empty.

Tested in the 12 possible combinations of:
 - PMUFW_INIT_FILE empty, relative, absolute, non-existing
 - building in-tree, in subdir, in other directory

efi_loader: avoid initializer element is not constant

When building with -pedantic the current definition of EFI_GUID() causes
an error 'initializer element is not constant'.

Currently EFI_GUID() is used both as an anonymous constant and as an
intializer. A conversion to efi_guid_t is not allowable when using
EFI_GUID() as an initializer. But it is needed when using it as an
anonymous constant.

We should not use EFI_GUID() for anything but an initializer. So let's
introduce a variable where needed and remove the conversion.

6 years agonet: designware: set the PS bit when resetting DMA bus in MII configuration
Quentin Schulz [Mon, 4 Jun 2018 10:17:33 +0000 (12:17 +0200)]
net: designware: set the PS bit when resetting DMA bus in MII configuration

On the SPEAr600 SoC, which has the dwmac1000 variant of the IP block,
the DMA reset never succeeds when a MII PHY is used (no problem with a
GMII PHY). The designware_eth_init() function sets the
DMAMAC_SRST bit in the DMA_BUS_MODE register, and then
polls until this bit clears. When a MII PHY is used, with the current
driver, this bit never clears and the driver therefore doesn't work.

The reason is that the PS bit of the GMAC_CONTROL register should be
correctly configured for the DMA reset to work. When the PS bit is 0,
it tells the MAC we have a GMII PHY, when the PS bit is 1, it tells
the MAC we have a MII PHY.

Doing a DMA reset clears all registers, so the PS bit is cleared as
well. This makes the DMA reset work fine with a GMII PHY. However,
with MII PHY, the PS bit should be set.

We have identified this issue thanks to two SPEAr600 platform:

- One equipped with a GMII PHY, with which the existing driver was
working fine.

- One equipped with a MII PHY, where the current driver fails because
the DMA reset times out.
