It looks like the flash controller is compatible, but the flash properties are different.

Dumping the flash descriptor on a simtrace2 I had with SAM3S2BA:

FL_ID = 0x000f0711
FL_SIZE = 131072
FL_PAGE_SIZE = 256
FL_PLANE[0] = 131072
FL_NB_LOCK[0] = 16384
FL_NB_LOCK[1] = 16384
FL_NB_LOCK[2] = 16384
FL_NB_LOCK[3] = 16384
FL_NB_LOCK[4] = 16384
FL_NB_LOCK[5] = 16384
FL_NB_LOCK[6] = 16384
FL_NB_LOCK[7] = 16384

Dumping the flash descriptor on a simtrace2 I have re-worked with SAM4S4BA:

FL_ID = 0x000f0730
FL_SIZE = 262144
FL_PAGE_SIZE = 512
FL_PLANE[0] = 262144
FL_NB_LOCK[0] = 8192
FL_NB_LOCK[1] = 8192
FL_NB_LOCK[2] = 8192
FL_NB_LOCK[3] = 8192
FL_NB_LOCK[4] = 8192
FL_NB_LOCK[5] = 8192
FL_NB_LOCK[6] = 8192
FL_NB_LOCK[7] = 8192
FL_NB_LOCK[8] = 8192
FL_NB_LOCK[9] = 8192
FL_NB_LOCK[10] = 8192
FL_NB_LOCK[11] = 8192
FL_NB_LOCK[12] = 8192
FL_NB_LOCK[13] = 8192
FL_NB_LOCK[14] = 8192
FL_NB_LOCK[15] = 8192
FL_NB_LOCK[16] = 8192
FL_NB_LOCK[17] = 8192
FL_NB_LOCK[18] = 8192
FL_NB_LOCK[19] = 8192
FL_NB_LOCK[20] = 8192
FL_NB_LOCK[21] = 8192
FL_NB_LOCK[22] = 8192
FL_NB_LOCK[23] = 8192
FL_NB_LOCK[24] = 8192
FL_NB_LOCK[25] = 8192
FL_NB_LOCK[26] = 8192
FL_NB_LOCK[27] = 8192
FL_NB_LOCK[28] = 8192
FL_NB_LOCK[29] = 8192
FL_NB_LOCK[30] = 8192
FL_NB_LOCK[31] = 8192

• the page size (256 -> 512) and
• the lock region size (16k->8k) has changed.

According to https://github.com/Microchip-Ethernet/EVB-KSZ9477/blob/0802dd40dc391aa580d15c59cbc0203eb8c699bc/KSZ/Atmel_SOC_SAMA5D3/buildroot/host/opt/sam-ba/applets/sam4s/libraries/libchip_sam4s/include/efc.h#L64 it seems that even atmel (at least in their softpack libraries) uses an hard-coded approach where the page size is a preprocessor #define rather than resolved at runtime from the flash descriptor.
