I'm wondering if this attempt to deal the gs1900 switch family really
improves the situation for these devices. While IMAGE_SIZE and
UIMAGE_MAGIC might indeed by rather generic to most (all?) members of
the gs1900 family, SOC might not be (GS1900-24, GS1900-24E, GS1900-24HP
are RTL8382M, GS1900-48 and GS1900-48HP are RTL8393 - admittedly, I do
not know how different the resulting DTS would need to be, as these
devices are not supported yet) and zyxel-vers is different for every
single model (aside from GS1900-8HPv1 && GS1900-8HPv2):

GS1900-8:	AAHH
GS1900-8HPv1:	AAHI
GS1900-8HPv2:	AAHI
GS1900-10HP:	AAZI
GS1900-16:	AAHJ
GS1900-24:	AAHL
GS1900-24E:	AAHK
GS1900-24EP:	ABTO
GS1900-24HP:	AAHM
GS1900-24HPv2:	ABTP
GS1900-48:	AAHN
GS1900-48HP:	AAHO
GS1900-48HPv2:	ABTQ

Most of these should be supportable by OpenWrt.
