25484d9070 xilinx: common: Fix boot script address
Currently u-boot supports addresses upto 39-bits only. If anybody
wants to use addresses of more than 39-bits in Linux they will have
a separate memory node in DT. In such cases they will have multiple
memory nodes.
Currently u-boot selects and runs on lower memory bank region.
But bootscript is being loaded on dram bank 0, where dram bank 0 will
point to 1st memory node in DT. If first memory node is mentioned as
higher ddr(>39-bits address) then u-boot cannot load the bootscript.
So fix this issue by setting bootscript address within the lower memory
bank region.

ef1be3e364 xilinx: zynqmp: Add usb dfu/thor distro boot support
In usb boot mode distro boot should select usb device as primary boot
device instead of usb host. So make usb dfu as primary boot device. But do
not list it in boot_targets as fallback option because it is not classic
mode for booting. Using 60s timeout by default should be enough time for
dfu-utils to start transaction. In case none needs this please change
timeout value in the command or disable CONFIG_DFU_TIMEOUT.

1238d0143a arm: highbank: Do DRAM init from DT
So far U-Boot was hard coding a (surely sufficient) memory size of 512
MB, even though all machines out there have at least 4GB of DRAM.
Since U-Boot uses its memory knowledge to populate the EFI memory map,
we are missing out here, at best losing everything beyond 4GB on Midway
boxes (which typically come with 8GB of DRAM).

Since the management processor populated the DT memory node already with
the detected DRAM size and configuration, we use that to populate
U-Boot's memory bank information, which is the base for the UEFI memory
map.
This finally allows us to get rid of the NR_DRAM_BANKS=0 hack, that we
had in place to avoid U-Boot messing up the DT memory node before
loading the kernel.

Also, to cover the whole of memory, we need to enable PHYS_64BIT.

ff47d539f2 arm: highbank: Remove artificial SDRAM size
So far we were defining a somewhat confusing PHYS_SDRAM_1_SIZE variable,
which originally was only used for setting the memtest boundaries. This
definition in highbank.h has been removed about a year ago (moved to
Kconfig), so we also don't need the hard-coded size definition any longer.

Get rid of the misleading memory size definition, which was actually wrong
anyway (it's 4088 MB for those machines with just 4GB of DRAM).

debb07bf10 net: calxedagmac: Convert to DM_ETH
To squash that nasty warning message and make better use of the newly
gained OF_CONTROL feature, let's convert the calxedagmac driver to the
"new" driver model.
The conversion is pretty straight forward, mostly just adjusting the
use of the involved data structures.
The only actual change is the required split of the receive routine into
a receive and free_pkt part.
Also this allows us to get rid of the hardcoded platform information and
explicit init calls.

This also uses the opportunity to wrap the code decoding the MMIO
register base address, to make it safe for using PHYS_64BIT later.

109552d773 arm: highbank: Enable OF_CONTROL
All Calxeda machines are actually a poster book example of device tree
usage: the DT is loaded from flash by the management processor into
DRAM, the memory node is populated with the detected DRAM size and this
DT is then handed over to the kernel.
So it's a shame that U-Boot didn't participate in this chain, but
fortunately this is easy to fix:

Define CONFIG_OF_CONTROL and CONFIG_OF_BOARD, and provide a trivial
function to tell U-Boot about the (fixed) location of the DTB in DRAM.
Then enable DM_SERIAL, to let the PL011 driver pick up the UART platform
data from the DT. Also define AHCI, to bring this driver into the driver
model world as well.

84b2cd74f3 arm: highbank: Limit FDT and initrd load addresses
So far on Highbank/Midway machines U-Boot only ever uses 512MB of DRAM,
even though the machines have typically 4GB and 8GB, respectively.
That means that so far we didn't need an extra limit for placing the DTB
and initrd, as the 512MB are lower than the kernel's limit ("lowmem",
typically 768MB).

With U-Boot now needing to learn about the actual memory size (to
correctly populate the EFI memory map), it might relocate fdt and initrd
to the end of DRAM, which is out of reach of the kernel.

So add limiting values to the fdt_high and initrd_high environment
variables, to prevent U-Boot from using too high addresses.

0a527fda78 Fix IDE commands issued, fix endian issues, fix non MMIO
Fixes IDE issues found on the Malta board under Qemu:

1) DMA implied commands were sent to the controller in stead of the PIO
variants. The rest of the code is DMA free and written for PIO operation.

2) direct pointer access was used to read and write the registers instead
of the inb/inw/outb/outw functions/macros. Registers don't have to be
memory mapped and ATA_CURR_BASE() does not have to return an offset from
address zero.

3) Endian isues in ide_ident() and reading/writing data in general. Names
were corrupted and sizes misreported.

Tested malta_defconfig and maltael_defconfig to work again in Qemu.

6f6876a0c0 arm64: gic-v3-its: Clear the Pending table before enabling LPIs
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.
