-Subject: [PATCH 130/203] mtd: nand: pxa3xx: Allocate data buffer on detected
- flash size
-
-This commit replaces the currently hardcoded buffer size, by a
-dynamic detection scheme. First a small 256 bytes buffer is allocated
-so the device can be detected (using READID and friends commands).
-
-After detection, this buffer is released and a new buffer is allocated
-to acommodate the page size plus out-of-band size.
