SPDX License cleanup for LiMon imported files

A number of network related files were imported from the LiMon
project; these contain a somewhat unclear license statement:

Copyright 1994 - 2000 Neil Russell.
(See License)

I analyzed the source code of LiMon v1.4.2 which was used for this
import.  It does not contain any "License" file, but the top level
directory contains a file "COPYING", which turns out to be GPL v2
of June 1991.  So it is legitimate to conclude that the LiMon derived
files are also to be released under GPLv2.  Mark them as such.

beagleboard: Remove side effects of i2c2 pullup resisters initialization code

Fix typo of commit d4e53f063dd25e071444b87303573e7440deeb89.

i2c2 pullup resisters are controlled by bit 0 of CONTROL_PROG_IO1.
It's value after reset is 0x00100001.

In order to clear bit 0, original code write 0xfffffffe to
CONTROL_PROG_IO1 and toggle almost all default values.

Original code affect following:
* disable i2c1 pullup resisters
* increase far end load setting for many modules
* setup invalid SC/LB combination

common/board_r: Fix booting issue on T4240QDS

Commit 294b91a5817147d4b7f47be2ac69bac2a1f26491 moved initr_malloc
earlier than initr_unlock_ram_in_cache. This causes issue on T4240.
It may be related to locked L1 d-cache and unlocked L2 cache. D-
cache could and should be unlock earlier for normal operation.

This patch moves initr_unlock_ram_in_cache before initr_malloc. It
has been verified on the following boards, in which only T4240QDS
suffered and has been since fixed: T4240QDS, T2080QDS, P5040DS,
P4080DS, MPC8572DS, MPC8536DS, MPC8641HPCN, B4860QDS.

pxe: Ensure we don't overflow bootargs

On a couple of platforms I've tripped over long PXE append lines overflowing
this array, due to having CONFIG_SYS_CBSIZE == 256. When doing preseeded Debian
installs it's pretty trivial to exceed that.

Since the symptom can be a silent hang or a crash add a check. Of course the
affected boards would also need an increased CBSIZE to actually work.

Note that due to the printing of the final bootargs string CONFIG_SYS_PBSIZE
also needs to be sufficiently large.

sunxi: Fix gmac not working reliable on the Bananapi

In order for the gmac nic to work reliable on the Bananapi, we need to set
bits 10-12 GTXDC "GMAC Transmit Clock Delay Chain" of the GMAC clk register
(0x01c20164) to 3.

Without this about 9 out of 10 ethernet packets get lost, with this setting
there is no packet loss.

So far setting these bits is only necessary on the Bananapi, so this commit
solves this with a bit of #ifdef CONFIG_BANANAPI code. If in the future we
need to do something similar for other boards, we can create a specific
CONFIG_FOO option for this then.

usb: musb-new: core: set MUSB_POWER_HSENAB in MUSB_POWER for host mode

This bit allows the MUSB controller to negotiate for high-speed mode when
the device is reset by the hub. If unset, Babble errors occur with
high-speed mass storage devices right after the first packet. This condition
is not caught by the interrupt handles in U-Boot, so no recovery is done,
and the USB communication is stuck.

To fix this, set the bit unconditionally, not only for
CONFIG_USB_GADGET_DUALSPEED but also for host-only modes.

since the file was a wild mess and it was impossible to make sense
of it's content, let alone change something without breaking some

standards.

Also remove unused preprocessor symbols CONFIG_SINGLE_BOOTOADER

logical reordering of the defines in the file so it's much more
readable. The reordering was also necessary for the splitting
as the initial one was messy.

tools: socfpga: Add socfpga preloader signing to mkimage

Like many platforms, the Altera socfpga platform requires that the
preloader be "signed" in a certain way or the built-in boot ROM will
not boot the code.

This change automatically creates an appropriately signed preloader
from an SPL image.

The signed image includes a CRC which must, of course, be generated
with a CRC generator that the SoCFPGA boot ROM agrees with otherwise
the boot ROM will reject the image.

Unfortunately the CRC used in this boot ROM is not the same as the
Adler CRC in lib/crc32.c. Indeed the Adler code is not technically a
CRC but is more correctly described as a checksum.

Thus, the appropriate CRC generator is added to lib/ as crc32_alt.c.

mmc: dw_mmc: Fix cache alignment issue

The DMA descriptors used by the DW MMC block must be aligned to cacheline
size, otherwise we are unable to properly flush/inval cache over them and
we get data corruption.

The reason I chose this approach of expanding the structure is because
the driver allocates the descriptors in bulk. This approach does waste
space by inserting slop inbetween the descriptors, but it makes access
to the descriptors easy as the compiler does know the real size of the
structure. It also makes cache operations easy, since the size of the
structure is cache aligned and the structure start address is as well.

usb: kbd: On a "usb reset" call usb_kbd_deregister() before calling usb_stop()

We need to call usb_kbd_deregister() before calling usb_stop().

usbkbd's stdio_dev->priv points to the usb_device, and usb_kbd_testc
dereferences usb_device->privptr.

usb_stop zeros usb_device, leaving usb_device->privptr NULL, causing
bad things (tm) to happen once control returns to the main loop and
usb_kbd_testc gets called.

Calling usb_kbd_deregister() avoids this. Note that we do not allow
the "usb reset" to continue when the deregister fails. This will be fixed
in a later patch.

When we first start an int queue, the qh's overlay area is all zeros. This

would think the transfer has completed as the hc has not yet copied the
qt_token to the overlay, so the active flag is not set.

This fixes this by checking the actual qtd token, rather then the overlay.
This also fixes a (theoretical) race where we see the completion in the
overlay and free and re-use the qtd before the hc has completed writing back
the overlay to the actual qtd.
