cmd: ubi: change 'default y' for SUNXI to 'imply' in Kconfig

2018-08-26T16:24:03+00:00

It is not preferred to put SUNXI-specific code in the common place.

Change it to 'imply' property of ARCH_SUNXI.

u-boot: align cache flushes in load_elf_image_shdr to line boundaries

2018-08-24T19:59:33+00:00

Prevent cache warning messages when using the 'bootelf' command on an
Arm target. Round down each section start address and round up the
respective section end to the nearest cache line.

Currently when using bootelf to load an image on Arm, several warnings
such as the following appear in the console:
  CACHE: Misaligned operation at range [87800000, 8783c5e0]
  CACHE: Misaligned operation at range [8783c5e0, 8784b3e0]

  - RTS fixes
  - implement reset for simple output

cmd: Add bind/unbind commands to bind a device to a driver from the command line

2018-08-21T14:21:37+00:00

In some cases it can be useful to be able to bind a device to a driver from
the command line.
The obvious example is for versatile devices such as USB gadget.
Another use case is when the devices are not yet ready at startup and
require some setup before the drivers are bound (ex: FPGA which bitsream is
fetched from a mass storage or ethernet)

usage example:

bind usb_dev_generic 0 usb_ether
unbind usb_dev_generic 0 usb_ether
or
unbind eth 1

bind /ocp/omap_dwc3@48380000/usb@48390000 usb_ether
unbind /ocp/omap_dwc3@48380000/usb@48390000

cmd: fastboot: Validate user input

2018-08-21T14:21:37+00:00

In case when user provides '-' as USB controller index, like this:

    => fastboot -

data abort occurs in strcmp() function in do_fastboot(), here:

    if (!strcmp(argv[1], "udp"))

(tested on BeagleBone Black).

That's because argv[1] is NULL when user types in the '-', and null
pointer dereference occurs in strcmp() (which is ok according to C
standard specification). So we must validate user input to prevent such
behavior.

While at it, check also the result of strtoul() function and handle
error cases properly.

efi: Add EFI_MEMORY_{NV, MORE_RELIABLE, RO} attributes

2018-08-20T22:03:56+00:00

With this update, the memory attributes are in sync with Linux
kernel v4.18-rc4. They also match page 190 of UEFI 2.7 spec [1].

efi: Fix truncation of constant value

2018-08-20T22:03:01+00:00

Starting with commit 867a6ac86dd8 ("efi: Add start-up library code"),
sparse constantly complains about truncated constant value in efi.h:

include/efi.h:176:35: warning: cast truncates bits from constant value (8000000000000000 becomes 0)

This can get quite noisy, preventing real issues to be noticed:

$ make defconfig
*** Default configuration is based on 'sandbox_defconfig'
$ make C=2 -j12 2>&1 | grep truncates | wc -l
441

After the patch is applied:
$ make C=2 -j12 2>&1 | grep truncates | wc -l
0
$ sparse --version
v0.5.2

Following the suggestion of Heinrich Schuchardt, instead of only
fixing the root-cause, I replaced the whole enum of _SHIFT values
by ULL defines. This matches both the UEFI 2.7 spec and the Linux
kernel implementation.

Some ELF size comparison before and after the patch (gcc 7.3.0):

cmd: Add dtimg command

2018-08-20T11:21:29+00:00

dtimg command allows user to work with Android DTB/DTBO image format.
Such as, getting the address of desired DTB/DTBO file, printing the dump
of the image in U-Boot shell, etc.

This command is needed to provide Android boot with new Android DT image
format further.
