2018-09-19tools: kwboot: Make kwboot more robust on a38xJon Nettleton
This patch accomplishes 2 things to make the kwboot procedure on the a38x more reliable. 1) We fill the tty with 1K of the magic bootparam. This helps with the timing of where the microcode picks up in the read of the line to ensure we actually catch the break to go into recovery mode 2) Before starting the xmodem transfer we sleep for 2 seconds and then flush the line. This allows all the magic bootparam to be flushed from the line and makes the xmodem transfer reliable and removes the Bad message failures.

2018-08-07tools: kwboot: properly quit when read() returns 0Willy Tarreau
When kwboot is attached to a terminal which disappears such as one connected via an unplugged USB cable, read() returns 0, making kwboot loop until a key is pressed in the terminal. The only case where read() may return 0 here is when the terminal is closed anyway, so let's properly handle this one and report is similar to other errors.

2018-08-07tools: kwboot: unbreak terminal-only modeWilly Tarreau
Commit 84899e2 ("tools/kwboot: Sync with latest barebox version to support Armada XP") accidently broke the terminal-only mode (-t) by removing the test on the bootmsg. Thus even when trying to use kwboot as a plain terminal, it asks to reboot the target. This commit simply reintroduces the lost test so that it is possible again to use kwboot to attach to the target system's console.

2017-02-17tools: kwboot: don't adjust destaddr when patching the imageChris Packham
Commit 94084eea3bd3 ("tools: kwbimage: Fix dest addr") changed kwbimage to do this adjustment. So now the adjustment in kwboot is not needed (and would prevent UART booting for images generated by the new kwbimage). Remove the destaddr adjustment in kwboot.

2016-08-26tools: kwboot: patch destaddr only for SoCs with header version 1Simon Baatz
Commit f4db6c976cf ("arm: mvebu: Add runtime detection of UART (xmodem) boot-mode") added a change to hdr->destaddr when dynamically patching an image for UART boot mode. With this change, kwboot ceases to work on Kirkwood. Thus, let's change hdr->destaddr only when we are patching an image with header version 1 (Orion and Kirkwood use header version 0).

2016-03-24tools: kwboot: Add xmodem timeout optionKevin Smith
Add command-line specification of xmodem timeout. If the binary header needs to take a while to do something (e.g. DDR ECC scrubbing), the xmodem transfer can time out. Add a configurable xmodem block timeout to allow transfers with slow binary headers to succeed.

2016-03-24tools: kwboot: Clean up usage textKevin Smith
Usage text was getting unwieldy and somewhat incorrect. The usage summary implied that some options were mutually exclusive (e.g. -q or -s). Clean up the summary to just include the important ones, and include a generic "[OPTIONS]" instead.

2016-01-14arm: mvebu: Add runtime detection of UART (xmodem) boot-modeStefan Roese
This patch adds runtime detection of the Marvell UART boot-mode (xmodem protocol). If this boot-mode is detected, SPL will return to the BootROM to continue the UART booting. With this patch its now possible, to generate a U-Boot image that can be booted either from the strapped boot-device (e.g. SPI NOR, MMC, etc) or via the xmodem protocol from the UART. In the UART case, the kwboot tool will dynamically insert the UART boot-device type into the image. And also patch the load address in the header, so that the mkimage header will be skipped (as its not expected by the Marvell BootROM). This simplifies the development for Armada XP / 38x based boards. As no special images need to be generated by selecting the MVEBU_BOOTROM_UARTBOOT Kconfig option. Since the Kconfig option MVEBU_BOOTROM_UARTBOOT is not needed any more, its now completely removed.

2015-10-01tools: kwboot: Add support for UART boot mode patching for Armada XP/38xStefan Roese
Currently, kwboot only allows dynamic UART boot mode patching for SoCs with header version 0 (Orion, Kirkwood). This patch now enables this "-p" feature also for SoCs with header version 1 (Armada XP / 38x etc). With this its possible now to use the UART boot mode without on images that are generated for other boot devices, like SPI. So no need to change BOOT_FROM to "uart" for UART xmodem booting any more.

2015-06-14tools/kwboot: Add parameters to set delay and timeout via cmdlineStefan Roese
To support the Armada 38x, new values for the request-delay and the response-timeout are needed. As the values already implemented in this tool (for Kirkwood and Armada XP) don't seem to work here. To make this more flexible, lets add make those 2 parameters configurable via the cmdline. Here the new parameters: -q <req-delay>: use specific request-delay -s <resp-timeo>: use specific response-timeout For the Marvell DB-88F6820 these values are known to work: One board: -q 2 -s 1 2nd board: -q 5 -s 5 So this seems to be even board specific. But with this patch now those values can be specified and tested via the cmdline.

2014-10-23tools/kwboot: Sync with latest barebox version to support Armada XPStefan Roese
The barebox version of the kwboot tool has evolved a bit. To support Armada XP and Dove. Additionally a few minor fixes have been applied. So lets sync with the latest barebox version. Please note that the main difference between both versions now is, that the U-Boot version still supports the -p option, to dynamically patch an image for UART boot mode. I didn't test it now though.
