[Damien Riegel]

This patchset brings the support for the TS-4800 manufactured by Technologic
Systems. While we're at it, rename the ts directory to technologic to be
consistent with Linux and U-Boot.

[Buildroot] [PATCH 1/2] board: rename ts to technologic

[Damien Riegel]

Other projects, such as Linux [1] and U-Boot [2], use "technologic" for
this manufacturer. To be more consistent across all of them, rename the
board/ts folder to board/technologic.

[Buildroot] [PATCH 2/2] configs: add defconfig for TS-4800

[Damien Riegel]

This patch adds support for the TS-4800 SoM manufactured by Technologic
Systems based on the Freescale i.MX515 SoC.

The TS-4800 is supported by mainline Linux as of 4.5. There are two
patches for U-Boot. The first one modifies the default environment to
more sane values. The second defines an errata that seems to affect the
board. These patches will be sent upstream and hopefully they will be
removed from Buildroot at some point.

mbrboot.bin is a MBR routine which was extracted from the image provided
by Technologic Systems. Basically, it scans every partition with the
0xda type and copies the first file to a given offset, and then jump
where the first file was copied to start its execution. In our case, we
use it to load u-boot. This routine is loaded by the companion FPGA and
the board won't be able to boot if this is missing.

A post-image script is provided to generate an image that can be "dd"
directly to an SD card.

More details on the board here:

+Subject: [PATCH] ts4800: add CONFIG_SYS_FSL_ERRATUM_ESDHC_A001
+
+This commit fixes the MMC data transactions timeout problem on the
+TS4800.
+
+The changes introduced in the commit e978a31 on the timeout calculation
+for the MMC data transactions has revealed there is something wrong with
+the timeout setting of the eSDHC controller used in the IMX51.
+
+The IMX51 seems to be concerned by this erratum and without this change
+the MMC driver is unable to do any transactions.

I think you said on IRC you would post a new version of this patch, so
I've marked this first version as "Changes Requested" in our patch
tracking system. So don't forget to send a new version, otherwise we'll
forget about it!

Thanks!

You're right, I asked you to delay the integration of this patch because
I got early feedbacks on IRC about one of the U-Boot patches (I was
messing with CONDIG_LOADADDR and that was just wrong). I'll send the v2
in a few minutes!

Thank you,
Damien
