*SOC_CHIP*
10 1 Eric Krausser

Usually ${TARGET_VENDOR}_${TARGET_DEVICE}
33 1 Eric Krausser

*WITH_USB*
35 1 Eric Krausser
36 1 Eric Krausser
If defined (e.g. set to WITH_USB=yes), build with kernel modules like usb, ehci, umass, etc. (see ./socs/${SOC_VENDOR}/${SOC_CHIP}/soc.mk).

38 1 Eric Krausser
*KERNCONF_MODULES_OVERRIDE*
39 1 Eric Krausser
40 13 Eric Krausser
Use this to append additional kernel modules, e.g. for some common USB stuff:
41 13 Eric Krausser
@KERNCONF_MODULES_OVERRIDE+=usb/uplcom usb/u3g usb/umodem usb/ucom cam zlib@
42 13 Eric Krausser
or for WLAN:
43 13 Eric Krausser
@KERNCONF_MODULES_OVERRIDE+=wlan_xauth wlan_wep wlan_tkip wlan_acl wlan_amrr wlan_ccmp wlan_rssadapt@

*FIRMWARE_IMAGE_SIZE_MAX*
62 1 Eric Krausser
63 12 Eric Krausser
The Image must not be bigger than the geom_map 'upgrade' partition (see [[Partition_layout]]), but other limitations can apply. For example NQ-900 has 32M of RAM and 16M of flash, but it is hard to download 16M image when you have only 32M of RAM.
