This patch adds TopBottom detection for most Macronix chips with CFI V1.0. The main purpose of this patch is to add detection of the MX29LV400C B used on the LaCie Ethernet Disk mini V2 NAS. It detects the following parts correctly:- MX28F640C3B T MX29LV002C B MX29LV002NC B MX29LV004C T MX29LV400C T/B MX29LV800C T/B MX29LV160C T/B MX29SL800C T/B MX29SL802C T/B It detects the following uniform part as bottom but it should work correctly:- MX29LV040C For T parts it causes the erase block table to be reversed correctly. For other parts it avoids the bogus "Assuming top" message. It does not detect the following correctly:- MX28F640C3B B MX29LV002C T MX29LV002NC T MX29LV004C B MX29SL400C T/B MX29SL402C T/B If desired I could supply a more complicated patch to handle these as well. Only the MX29LV400C B has been physically tested; others were checked against their data sheets.
