[U-Boot] [RFC PATCH] arm, Makefile: set SPL_PAYLOAD according to the SoC architecture
by Raghav Dogra 16 Sep '16

16 Sep '16

SPL_PAYLOAD should be .img in case of ARM architecture and .bin in case of other architectures. This patch takes care of the same by choosing the SPL_PAYLOAD as u-boot.img for ARM architecture and u-boot.bin for others.

[U-Boot] [PATCH v5 0/5] various fixes mainly for colibri_t20
by Marcel Ziswiler 16 Sep '16

16 Sep '16

This series addresses various issues as seen on Colibri T20. Please note that for successful Ethernet operation not only on Colibri T20 but also on Colibri T30 the following patch will still be required already waiting in Marek's usb tree: [PATCH v2] net: asix: Fix ASIX 88772B with driver model https://www.mail-archive.com/u-boot@lists.denx.de/msg224349.html Changes in v5: - Remove DEBUG define. - Put the " - not found! Error" back into the debug message as suggested by Stephen. - Add Stephen's ack. Changes in v4: - Use full regulator rather than reg wording again in debug message as suggested by Przemyslaw. - Tighten up error handling as suggested by John. - Fix set_enable() as suggested by Stephen. - Add Stephen's ack. Changes in v3: - Add Stephen's ack. - Introduce new patch to honour optionality of fixed regulator enable GPIO. - Get rid of dummy N/C GPIO work around now as the fixed regulator properly honours optionality of enable GPIO. - Add Stephen's ack. Changes in v2: - As suggested by Stephen gating the CONFIG_CI_UDC_HAS_HOSTPC define with CONFIG_TEGRA20 rather than duplicating the same into all other SoC type specific header files. - Add Anatolij's ack. - Rename dummy regulator to reg_3v3 as suggested by Stephen. - Keep dummy N/C GPIO to work around bug in U-Boot regulator driver requiring such node despite its binding claiming it being optional. - As suggested by Stephen remove last patch 5/5 colibri_t20: enable dfu also for nand.

[U-Boot] [PATCH 0/5] toradex: config block handling
by Marcel Ziswiler 16 Sep '16

16 Sep '16

This series integrates Toradex factory configuration block handling. The config block is a data structure which gets stored to flash during production testing. The structure holds such information as board resp. hardware revision, product ID and serial number which is used as the NIC part of the Ethernet MAC address as well. The config block will be read upon boot by the checkboard() function, displayed as part of the board information and passed to Linux via device tree or ATAGs.

[U-Boot] how to programatically add a second hash table to the environment?
by Robert P. J. Day 16 Sep '16

16 Sep '16

i'm hoping this is a simple question -- at boot time, i've added a misc_init_r() routine that digs around in some legacy flash, pulls out a string of (vxworks) "var=val" settings, and imports that in one shot into an initial hash table. works fine. as the second step, i walk that table and, for the vxworks settings i care about, i translate them to u-boot env variable names, possibly massage the data values, and add those values to a *second* hash table that now contains proper keys and values as u-boot would understand them. (for example, vxworks would have "g=gateway", whereas i translate that to "gatewayip=gateway" for the second hash table.) i now want to just add/overwrite the current u-boot environment with what's in that second hash, and as i see it, i could just walk that second hash and, for each ENTRY, do a call to hsearch_r() referring to the hash table "env_htab", yes? i see no single call that allows me to combine hash tables, but it's not as if i will have a lot of values to enter, so is that the right approach -- just a short series of calls of the form: hsearch_r(entry, ENTER, &ep, &env_htab, 0); seems straightforward enough, just want to confirm i'm not overlooking anything. rday -- ======================================================================== Robert P.

[U-Boot] [PATCH 1/7] i2c: mv_i2c.c: cosmetic: Coding style cleanups
by Stefan Roese 16 Sep '16

16 Sep '16

Some mostly indentation coding style cleanups. Also, move this driver to use debug() for debug output.
