usb: gadget: g_dnl: Sync internal SN variable with env

2017-09-06T00:17:08+00:00

Since commit 842778a09104 ("usb: gadget: g_dnl: only set iSerialNumber
if we have a serial#") "fastboot devices" stopped to show correct device
serial number for TI boards, showing this line instead:

    ????????????	fastboot

This is because serial# env variable could be set after g_dnl gadget was
initialized (e.g. by using env_set() in the board file).

To fix this, let's update internal serial number variable (g_dnl_serial)
when "serial#" env var is changed.

spl: add serial download protocol (SDP) support

2017-08-23T08:41:58+00:00

Add USB serial download protocol support to SPL. If the SoC started
in recovery mode the SPL will immediately switch to SDP and wait for
further downloads/commands from the host side.

usb: gadget: sdp: extend images compatible for jumps

2017-08-23T08:41:58+00:00

Support U-Boot images in SPL so that u-boot.img files can be
directly downloaded and executed. Furthermore support U-Boot
scripts download and execution in full U-Boot so that custom
recovery actions can be downloaded from the host in a third
step.

usb: gadget: add SDP driver

2017-08-23T08:41:58+00:00

Add SDP (Serial Downloader Protocol) implementation for U-Boot. The
protocol is used in NXP SoC's boot ROM and allows to download program
images. Beside that, it can also be used to read/write registers and
download complete Device Configuration Data (DCD) sets. This basic
implementation supports downloading images with the imx header format
reading and writing registers.

fastboot: Ensure we treat CONFIG_FASTBOOT_BUF_ADDR as long

fastboot: avoid printing invalid data

2017-08-21T09:31:10+00:00

There is no guarantee that commands are null-terminated in the USB
request buffer, so limit the length of data that is printed.

Fix fastboot boot address

2017-08-21T09:31:10+00:00

Fastboot loads an image at CONFIG_FASTBOOT_BUF_ADDR, but currently
tells do_bootm() to look for an image at $loadaddr.  This breaks if
CONFIG_FASTBOOT_BUF_ADDR is different from the current user-set
loadaddr.

Instead, tell do_bootm() to pick up the image where it was laoded.

env: Rename getenv/_f() to env_get()

2017-08-16T12:30:24+00:00

We are now using an env_ prefix for environment functions. Rename these
two functions for consistency. Also add function comments in common.h.

Quite a few places use getenv() in a condition context, provoking a
warning from checkpatch. These are fixed up in this patch also.
