e7ab86d9b2 net: rtl8139: Fill in SPDX tag
The rtl8139 driver is derived from Etherboot driver, which is in
turn derived from Linux 8139too driver added in Linux 2.2.18pre14.
An undocumented change in Linux 2.4.10.2 added a new field to the
driver, MODULE_LICENSE("GPL"); . According to current Linux kernel
licensing rules, Documentation/process/license-rules.rst, quote:

	"GPL"	Module is licensed under GPL version 2. This
		does not express any distinction between
		GPL-2.0-only or GPL-2.0-or-later. The exact
		license information can only be determined
		via the license information in the
		corresponding source files.

And since the code does not contain any "future" clause, the tag
is therefore GPL-2.0 only.

24891dd8d4 net: dwc_eth_qos: Prevent DMA from writing updated RX DMA descriptor
The DMA may attempt to write a DMA descriptor in the ring while it is
being updated. By writing the DMA descriptor buffer address to 0, it
is assured the DMA will not use such a buffer and the buffer can be
updated without any interference.

a83ca0c280 net: dwc_eth_qos: Invalidate RX packet DMA buffer
This patch prevents an issue where the RX packet might have been
accessed by the CPU, which now has cached data from the packet in
the caches and possibly various write buffers, and these data may
be evicted from the caches into the DRAM while the buffer is also
written by the DMA.

By invalidating the buffer after the CPU accessed it and before the
DMA populates the buffer, it is assured that the buffer will not be
corrupted.

738ee270fe net: dwc_eth_qos: Invalidate RX descriptor before reading
The current code polls the RX desciptor ring for new packets by reading
the RX descriptor status. This works by accident, as the RX descriptors
are often in non-cacheable memory. However, the driver does support use
of RX descriptors in cacheable memory.

This patch adds a missing RX descriptor invalidation, which assures the
CPU will read a fresh copy of the RX descriptor instead of a cached one.

83858d8795 net: dwc_eth_qos: Correctly wrap around TX descriptor tail pointer
This code programs the next descriptor in the TX descriptor ring into
the hardware as the last valid TX descriptor. The problem is that if
the currenty descriptor is the last one in the array, the code will
not wrap around correctly and use TX descriptor 0 again, but instead
will use TX descriptor at address right past the TX descriptor ring,
which is the first descriptor in the RX ring.

Fix this by adding the necessary wrap-around.

4332d80617 net: dwc_eth_qos: Fully rewrite RX descriptor field 3
The RX descriptor field 3 should contain only OWN and BUF1V bits before
being used for receiving data by the DMA engine. However, right now, if
the descriptor was already used for receiving data and is being cleared,
the field 3 is only modified and the aforementioned two bits are ORRed
into the field. This could lead to a residual dirty bits being left in
the field 3 from previous transfer, and it generally does. Fully set the
field 3 instead to clear those residual dirty bits.

86ee14f58b x86: Use the existing stack when chain-loading
With chromebook_coral we normally run TPL->SPL->U-Boot. This is the
'bare metal' case.

When running from coreboot we put u-boot.bin in the RW_LEGACY portion
of the image, e.g. with:

   cbfstool image-coral.serial.bin add-flat-binary -r RW_LEGACY \
	-f /tmp/b/chromebook_coral/u-boot.bin -n altfw/u-boot \
	-c lzma -l 0x1110000 -e 0x1110000

In this case U-Boot is run from coreboot (actually Depthcharge, its
payload) so we cannot access CAR. Use the existing stack instead.

cfe7a1068b x86: Add a way to detect running from coreboot
If U-Boot is running from coreboot we need to skip low-level init. Add
an way to detect this and to set the gd flag.

33139a0bc7 x86: Move coreboot-table detection into common code
To support detecting booting from coreboot, move the code which locates
the coreboot tables into a common place. Adjust the algorithm slightly to
use a word comparison instead of string, since it is faster.

ba974a0137 board: Add a gd flag for chain loading
When U-Boot is run from another boot loader, much of the low-level init
needs to be skipped.

Add a flag for this and adjust ll_boot_init() to use it.

f1f4438218 pci: Avoid auto-config when chain loading
When U-Boot is not the first-stage bootloader we don't want to
re-configure the PCI devices, since this has already been done. Add a
check to avoid this.

526aabec24 x86: cpu: Skip init code when chain loading
When U-Boot is not the first-stage bootloader the interrupt and cache init
must be skipped, as well as init for various peripherals. Update the code
to add checks for this.
