boundary: add new bootscript folder

Based on 6x_bootscript*.txt but using the variables name from
config_distro_bootcmd.h.

Also using $prefix as $bootdir for Yocto and Mainline versions.
boundary: bootscript: yocto: remove obsolete commands
boundary: bootscripts: fix bad disk variable replacement
boundary: bootscripts: net_upgradeu_fs: fix loaded script name
boundary: bootscripts: net_upgradeu_fs: update to match distro_bootcmd
boundary: bootscripts: add README file
boundary: bootscripts: rename folder to be plural
boundary: bootscripts: net_upgradeu_fs: remove active_partition

boundary: bootscripts: add upgrade.txt
boundary: bootscripts: s/\${cpu}/\${imx_cpu}/g

cpu already has a standard definition. Move to imx_cpu
so that eventual we can also use the standard definition of cpu.

boundary: bootscripts: s/dtbname/fdt_file/g

Again fdt_file seems to be the standard for which dtb
file to load. Noone else uses dtbname.

boundary: bootscripts: remove references to ${bootdir}, or replace with ${prefix}
boundary: bootscripts: net_upgrade_fs=net_upgrade_fs.scr
boundary: bootscripts: prevent hdmi audio from being card 0
boundary: bootscripts: ubuntu: check for console environment var before adding to bootargs
boundary: bootscripts: upgrade: check for chip at45db041d so that erase is not too big for chip
boundary: bootscripts: net_upgradeu: check for chip at45db041d so that erase is not too big for chip

boundary: honor distro_bootpart in u-boot upgrade

upgrade.txt hard codes all file accesses to partition 1 instead of
honoring the standard u-boot variable distro_bootpart.

Replace all occurrences of ${devnum}:1 with ${devnum}:${distro_bootpart}

+Boot scripts
+============
+
+This folder contains all the boot scripts for booting / upgrading any OS:
+* `bootscript-mainline.txt`: boot script for any OS using mainline-based kernel
+* `bootscript-ubuntu.txt`: boot script for Ubuntu OS using NXP-based kernel
+* `bootscript-yocto.txt`: boot script for Yocto OS using NXP-based kernel
+* `net_upgrade_fs.txt`: downloads `${upgrade_file}` over TFTP and flashes it into `${upgrade_device}`
+* `net_upgradeu_fs.txt`: downloads `${net_upgrade_fs}` over TFTP and executes it
+* `net_upgradeu.txt`: downloads `u-boot.${uboot_defconfig}` over TFTP and flashes it into NOR flash
+* `prog_fuses.txt`: program the fuses for both MAC address and boot selection
+* `upgrade.txt`: downloads `u-boot.${uboot_defconfig}` from local media and flashes it into NOR flash
+
+Those `.txt` files need to be transformed into U-Boot scripts (`.scr`) using `mkimage`.
+
+Here is an example for generating a `boot.scr` for Yocto OS:
+```
+mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n "bootscript" -d bootscript-yocto.txt boot.scr
+```
