+# The RAM+flash MCP in the GTA02 GSM modem block is SEC K5A3281CTM.
+# The closest datasheet that could be found is for K5A3280;
+# all current understanding of this IC is based on the latter datasheet.
+
+# The flash part of the MCP is wired to nCS0.  The access time is 70 ns
+# just like on the flash part used in the Pirelli DP-L10, so use the
+# same setting.

+# The RAM part of this MCP (wired to nCS1 as usual) appears to be real
+# SRAM, not pSRAM like in S71PL129NC0.  The access time is advertised
+# as 55 ns, and OsmocomBB sets WS to 3.  We'll do the same.
