The GICv3 RM requires "The first 1KB of memory for the LPI Pending tables
must contain only zeros on initial allocation, and this must be visible
to the Redistributors, or else the effect is UNPREDICTABLE".
And as the following statement, we here clear the whole Pending tables
instead of the first 1KB.
"An LPI Pending table that contains only zeros, including in the first 1KB,
indicates that there are no pending LPIs.
The first 1KB of the LPI Pending table is IMPLEMENTATION DEFINED. However,
if the first 1KB of the LPI Pending table and the rest of the table contain
only zeros, this must indicate that there are no pending LPIs."
And there isn't any pending LPI under U-Boot, so it's unnecessary to
load the contents of the Pending table during the enablement, then set
the GICR_PENDBASER.PTZ flag.

Merge tag 'u-boot-atmel-2021.07-b' of https://source.denx.de/u-boot/custodians/u-boot-atmel
Second set of u-boot-atmel features for 2021.07 cycle:
This small feature set include support for 5th PIO bank on pio4 pinctrl
driver and a fix for the SPL on sama5d3.
This reverts commit 38d6b7ebda.
struct global_data contains a pointer to the bd_info structure. This
pointer was populated spl_set_bd() to a pre-allocated bd_info in the
".data" section. The referenced commit replaced this mechanism to one
that uses malloc(). That new mechanism is only used if SPL_ALLOC_BD=y.
which very few boards do.
The result is that (struct global_data)->bd is NULL in SPL on most
platforms. This breaks falcon mode, since arch_fixup_fdt() tries to
access (struct global_data)->bd and set the "/memory" node in the
devicetree. The result is that the "/memory" node contains garbage
values, causing linux to panic() as it sets up the page table.
Instead of trying to fix the mess, potentially causing other issues,
revert to the code that worked, while this change is reworked.

This is a patchset which makes away with the .bind() controller indexing
workaround which was broken since before v2021.04, and then adds PHY
support and MX8M support on top of that. Better add it into the release
early to get as much testing as possible done, because this really does
a lot of changes to the ehci-mx6 driver.

In order to pass component addresses around easily instead of passing

in DM case.
