+title: Qualcomm External Bus Interface 2 (EBI2)
+
+description: |
+ The EBI2 contains two peripheral blocks: XMEM and LCDC. The XMEM handles any
+ external memory (such as NAND or other memory-mapped peripherals) whereas
+ LCDC handles LCD displays.
+
+ As it says it connects devices to an external bus interface, meaning address
+ lines (up to 9 address lines so can only address 1KiB external memory space),
+ data lines (16 bits), OE (output enable), ADV (address valid, used on some
+ NOR flash memories), WE (write enable). This on top of 6 different chip selects
+ (CS0 thru CS5) so that in theory 6 different devices can be connected.
+
+ Apparently this bus is clocked at 64MHz. It has dedicated pins on the package
+ and the bus can only come out on these pins, however if some of the pins are
+ unused they can be left unconnected or remuxed to be used as GPIO or in some
+ cases other orthogonal functions as well.
+
+ Also CS1 and CS2 has -A and -B signals. Why they have that is unclear to me.
+
+ The chip selects have the following memory range assignments. This region of
+ memory is referred to as "Chip Peripheral SS FPB0" and is 168MB big.
+
+ Chip Select Physical address base
+ CS0 GPIO134 0x1a800000-0x1b000000 (8MB)
+ CS1 GPIO39 (A) / GPIO123 (B) 0x1b000000-0x1b800000 (8MB)
+ CS2 GPIO40 (A) / GPIO124 (B) 0x1b800000-0x1c000000 (8MB)
+ CS3 GPIO133 0x1d000000-0x25000000 (128 MB)
+ CS4 GPIO132 0x1c800000-0x1d000000 (8MB)
+ CS5 GPIO131 0x1c000000-0x1c800000 (8MB)
+
+ The APQ8060 Qualcomm Application Processor User Guide, 80-N7150-14 Rev. A,
+ August 6, 2012 contains some incomplete documentation of the EBI2.
+
+ FIXME: the manual mentions "write precharge cycles" and "precharge cycles".
+ We have not been able to figure out which bit fields these correspond to
+ in the hardware, or what valid values exist. The current hypothesis is that
+ this is something just used on the FAST chip selects and that the SLOW
+ chip selects are understood fully. There is also a "byte device enable"
+ flag somewhere for 8bit memories.
+
+ FIXME: The chipselects have SLOW and FAST configuration registers. It's a bit
+ unclear what this means, if they are mutually exclusive or can be used
+ together, or if some chip selects are hardwired to be FAST and others are SLOW
+ by design.
+
+ The XMEM registers are totally undocumented but could be partially decoded
+ because the Cypress AN49576 Antioch Westbridge apparently has suspiciously
+ similar register layout, see: http://www.cypress.com/file/105771/download

+ The Address Mapping Control Register (AMCR) is used to split the 256MB
+ memory map area shared between the 2 OSPI instance. The Octo Memory
+ Manager sets the AMCR depending of the memory-region configuration.
+ The memory split bitmask description is:

+ - 001: OCTOSPI1 (192 Mbytes), OCTOSPI2 (64 Mbytes)
