The patch fixes a corner case where adding size to DRAM start resulted
in a value (1 << 32), which in turn overflew the u32 computation, which
resulted in 0 and it therefore prevented correct setup of the MMU tables.The addition of DRAM bank start and it's size can end up right at the end
of the address space in the special case of a machine with enough memory.
To prevent this overflow, shift the start and size separately and add them
only after they were shifted.Hopefully, we only have systems in tree which have DRAM size aligned to
1MiB boundary. If not, this patch would break such systems. On the other
hand, such system would be broken by design anyway.Signed-off-by: Marek Vasut

The Broadcom StarFighter2 Ethernet driver is used in multiple Broadcom
SoC(s) and:
- supports multiple MAC blocks,
- provides support for the Broadcom GMAC.

To enable hypervisors utilizing the ARMv7 virtualization extension

and add the required configuration variables to switch all cores to
HYP mode before launching the OS.

When compiling u-boot with W=1 the extern inline void for
read* is likely causing the most noise. gcc / clang will
warn there is never a actual declaration for these functions.
Instead of declaring these extern make them static inline so
it is actually declared.cc: Albert ARIBAUD

One specific USB 3.0 device behaves strangely when reset by
usb_new_device()'s call to hub_port_reset(). For some reason, the device
appears to briefly drop off the bus when this second bus reset is
executed, yet if we retry this loop, it'll eventually come back after
another two resets.If USB bus reset is executed over and over within usb_new_device()'s call
to hub_port_reset(), I see the following sequence of results, which
repeats as long as you want:1) STAT_C_CONNECTION = 1 STAT_CONNECTION = 0 USB_PORT_STAT_ENABLE 0
2) STAT_C_CONNECTION = 1 STAT_CONNECTION = 1 USB_PORT_STAT_ENABLE 0
3) STAT_C_CONNECTION = 1 STAT_CONNECTION = 1 USB_PORT_STAT_ENABLE 1The device in question is a SanDisk Ultra USB 3.0 16GB memory stick with
USB VID/PID 0x0781/0x5581.In order to allow this device to work with U-Boot, ignore the
{C_,}CONNECTION bits in the status/change registers, and only use the
ENABLE bit to determine if the reset was successful.To be honest, extensive investigation has failed to determine why this
problem occurs. I'd love to know! I don't know if it's caused by:
* A HW bug in the device
* A HW bug in the Tegra USB controller
* A SW bug in the U-Boot Tegra USB driver
* A SW bug in the U-Boot USB coreThis issue only occurs when the device's USB3 pins are attached to the
host; if only the USB2 pins are connected the issue does not occur. The
USB3 controller on Tegra is in reset, so is not actively communicating
with the device at all - a USB3 analyzer confirms this. Slightly
unplugging the device (so the USB3 pins don't contact) or using a USB2
cable or hub as an intermediary avoids the problem. For some reason,
the Linux kernel (either on the same Tegra board, or on an x86 host)
has no issue with the device, and I observe no disconnections during
reset.This change won't affect any USB device that already works, since such
devices could not currently be triggering the error return this patch
removes, or they wouldn't be working currently.However, this patch is quite reliable in practice, hence I hope it's
acceptable to solve the problem.The only potential fallout I can see from this patch is:
* A broken device that triggers C_CONNECTION/!CONNECTION now causes the
loop in hub_port_reset() to run multiple times. If it never succeeds,
this will cause "usb start" to take roughly 1s extra to execute.* If the user unplugs a device while hub_port_reset() is executing, and
very quickly swaps in a new device, hub_port_reset() might succeed on
the new device. This would mean that any information cached about the
original device (from the descriptor read in usb_new_device(), which
simply caches the max packet size) might be invalid, which would cause
problems talking to the new device. However, without this change, the
new device wouldn't work anyway, so this is probably not much of a
loss.Signed-off-by: Stephen Warren

As we support both Host and Device mode operation, an OTG controller
can return -ENODEV on a port which it found to be in Device mode during
Host mode scan for devices. In case -ENODEV is returned, print that the
port is not available and continue instead of screaming a bloody error
message.Signed-off-by: Marek Vasut

We noticed on the DXR2 platform (AM335x with a SMSC LAN9303 switch connected
to the CPSW MAC) that the network performance in U-Boot is quite poor. Only
when the transfer is started without a cable connected, and the cable is
plugged after the first timeout "T" occured, an increased in performance
can be seen. Debugging has revealed, that the cpsw driver has constant
link checking builtin into the rx and tx functions. This results in the
bad performance and seems to be unnecessary. The link has already been
checked in the init function, before the transfer is started. This usually
is sufficient.BTW: I have seen no other network driver in U-Boot so far, that constantly
checks for link in the rx / tx functions.The performance numbers on the DXR2 board are:
0.56 MiB/s cpsw_check_link() in rx and tx path
0.87 MiB/s cpsw_check_link() only in tx path
1.0 MiB/s cpsw_check_link() only in rx path
2.7 MiB/s no cpsw_check_link() in rx and tx pathSo with this patch the network performance on DXR2 increases from 0.56
to 2.7 MiB/s (nearly 5 times as fast).Signed-off-by: Stefan Roese

I guess some developers are already getting sick of this tool
because it generally takes a few minites to generate the boards.cfg
on a reasonable computer.The idea popped up on my mind was to skip Makefiles and
to run script/kconfig/conf directly.
This tool should become about 4 times faster.
You might still not be satisfied, but better than doing nothing.Signed-off-by: Masahiro Yamada

It looks silly to regenerate the boards.cfg even when it is
already up to date.The tool should exit with doing nothing if the boards.cfg is newer
than any of defconfig, Kconfig and MAINTAINERS files.Specify -f (--force) option to get the boards.cfg regenerated
regardless its time stamp.Signed-off-by: Masahiro Yamada

This tool deletes the incomplete boards.cfg
if it encounters an error or is is terminated by the user.I notice some problems even though they rarely happen.
[1] The boards.cfg is removed if the program is terminated
during __gen_boards_cfg() function but before boards.cfg
is actually touched. In this case, the previous boards.cfg
should be kept as it is.[2] If an error occurs while deleting the incomplete boards.cfg,
the program throws another exception. This hides the privious
exception and we will not be able to know the real cause.Signed-off-by: Masahiro Yamada

When an error occurs or the program is terminated by the user
on the way, the destructer __del__ of class Slot is invoked and
the work directories are removed.We have to make sure there are no subprocesses (in this case,
"make O= ...") using the work directories before
removing them. Otherwise the subprocess spits a bunch of error
messages possibly causing more problems. Perhaps some users
may get upset to see too many error messages.Signed-off-by: Masahiro Yamada

Commit e3a5bbce broke the FIT image tests by not loading a ramdisk even if
a load address is provided in the FIT. The rationale was that a load address
of 0 should be considered to mean 'do not load'.Add a new load operation which supports this feature, so that the ramdisk
will be loaded if a non-zero load address is provided.Signed-off-by: Simon Glass
