On some SoCs, DMA-capable peripherals see a different address space to
the CPU's physical address space. Create an API to allow platform-agnostic
drivers to convert between the two address spaces when programming DMA
operations.This API will exist on all platforms, but will have a dummy implementation
when this feature is not required. Other platforms will enable
CONFIG_PHYS_TO_BUS and provide the required implementation.Signed-off-by: Stephen Warren

When I created wait_for_chhltd(), I noticed that some instances of the
code it replaced expected the ACK bit to be set and others didn't. I
assumed this was an accidental inconsistency in the code, so wrote
wait_for_chhltd() to always expect ACK to be set. This code appeared to
work correctly for both enumeration of USB keyboards and operation of
USB Ethernet devices. However, this change broke USB Mass Storage (at
least my USB SD card reader). This change reverts to exactly the
original behaviour. I'm not sure why the ACK bit isn't always set
(perhaps a quirk in the USB HW or DWC2 controller), but the code works
this way!Fixes: 5be4ca7d6ac8 ("usb: dwc2: unify waiting for transfer completion")

Each USB transfer is split up into chunks that are held in an aligned
buffer. This imposes a limit on the size of each chunk, but no limit on
the total size of transferred data. Fix the logic in chunk_msg() not to
reject large transfers, but simply take the size of the aligned buffer
into account when calculating the chunk size.Signed-off-by: Stephen Warren
-
The original aligned_buffer usage:
a) Uselessly copied data into the aligned buffer even for IN
transactions. Fix this my making the copy conditional.
b) Always programmed the HW to transfer to/from the start of the aligned
buffer. This worked fine for OUT transactions since the memcpy copied
the OUT data to this location too. However, for large IN transactions,
since the copy from the aligned buffer to the "client" buffer was
deferred until after all chunks were transferred. it resulted in each
chunk's transfer over-writing the data for the first transfer. Fix
this by copying IN data as soon as it's received.Signed-off-by: Stephen Warren

toggle is never NULL. Simplify the code by removing handling of when it
is NULL.Signed-off-by: Stephen Warren
-
The control data toggle resets to DATA1 at the start of the data phase
of every setup transaction. We don't need a global variable to store
the value; we can just store it on the stack.Signed-off-by: Stephen Warren

Move the body of submit_bulk_msg() into new function chunk_msg(). This
can be shared with submit_control_msg() to reduce code duplication, and
allow control messages larger than maxpacket.Signed-off-by: Stephen Warren

Some USB devices break the spec and require longer warm-up times. Allow

When fetching the first descriptor from a new device, only validate that
we received at least 8 bytes, not that we received the entire descriptor.
The reasoning is:
- The code only uses fields in the first 8 bytes, so that's all we need
to have fetched at this stage.
- The smallest maxpacket size is 8 bytes. Before we know the actual
maxpacket the device uses, the USB controller may only accept a single
packet (see the DWC2 note in the comment added in the commit).
Consequently we are only guaranteed to receive 1 packet (at least 8
bytes) even in a non-error case.Fixes: 1a7758044b04 ("usb: Early failure when the first descriptor read
fails or is invalid")

This may happen when using an USB1 device on a controller that only supports
USB2 (e.g. EHCI). Reading the first descriptor will fail (read 0 byte), so we
can abort the process at this point instead of failing later and wasting time.Signed-off-by: Paul Kocialkowski

This checks that a new USB device is correctly initialized and frees it if not.
In addition, this doesn't report that USB was started when no device was found.Signed-off-by: Paul Kocialkowski

This patch fixes USB storage capacity detection breakage on 64-bit systems
which arises due to 'unsigned long' length difference. Old code assumes that
to be 32 bit and breaks because of inappropriate response buffer layout.
Also this fixes a number of build warnings and changes big-endian values

Since commit 79d75d752717 (ARM: move -march=* and -mtune= options to
arch/arm/Makefile), all the Tegra boards are broken because the SPL
is built for ARMv7.Insert Tegra-specific code to arch/arm/Makefile to set compiler
flags for an earlier ARM architecture.Note:
The v1 patch for commit 79d75d752717 *was* correct when it was
submitted. Notice it was originally written for multi .config
configuration where Kconfig set CONFIG_CPU_V7/CONFIG_CPU_ARM720T for
Tegra U-Boot Main/SPL, respectively. But, until it was merged into
the mainline, commit e02ee2548afe (kconfig: switch to single .config
configuration) had been already applied there.Signed-off-by: Masahiro Yamada

This modifies the vexpress64 Juno configuration so that
it will by default load and boot a kernel and a device tree
from the images stored in the NOR flash. When we are
at it, also define the proper command line for the Juno and

The ARM reference designs all use a special flash image format
that stores a footer (two versions exist) at the end of the last
erase block of the image in flash memory.Version one of the footer is indicated by the magic number
0xA0FFFF9F at 12 bytes before the end of the flash block and
version two is indicated by the magic number 0x464F4F54 0x464C5348
(ASCII for "FLSHFOOT") in the very last 8 bytes of the erase block.This command driver implements support for both versions of the
AFS images (the name comes from the Linux driver in drivers/mtd/afs.c)
and makes it possible to list images and load an image by name into
the memory with these commands:afs - lists flash contents
afs load - loads image to address indicated in the image
afs load - loads image to a specified addressThis image scheme is used on the ARM Integrator family, ARM
Versatile family, ARM RealView family (not yet supported in U-Boot)
and ARM Versatile Express family up to and including the new
Juno board for 64 bit development.Reviewed-by: Tom Rini

The ubi check command is expected to not fail and just check whether
a volume exist or not. Currently, when a volume does not exist, the
command fails which leads to an error:
"exit not allowed from main input shell."Use 1 to indicate that a volume does not exist. This allows to use
ubi check in an if statement, e.g.
if ubi check rootfs; then; echo "exists"; else; echo "not there"; fi -
This is important to have entry point in the beginning of .text section
because it allows simple loading and execution of U-Boot.For example pre-bootloader loads U-Boot in memory starting from offset
0x81000000 and then just jumps to the same address.Otherwise pre-bootloader would need to find-out where entry-point is. In
its turn if it deals with binary image of U-Boot there's no way for
pre-bootloader to get required value.Signed-off-by: Alexey Brodkin
