Squashed commit of the following:
BCM2708: Add enough infrastructrue (more stubs) to get a clean compilation of the Pi Zero configuration (with many undefined things at link time).
BCM2708: Add basic interrupt handling logic
BCM2708: Add interrupt register definitions.
BCM2708: Add irq.h header file
BCM2708/Pi zero: bcm_boot.c and bcm_memorymap.h now compile. Added pizero linker script.
BCM2708/Pi Zero: Add Make.defs needed to build.
arch/arm/include/bcm2708, arch/arm/src/bcm2708, configs/pizero: Add some basic build and configuration logic.
configs/pizero: Add some basic structure of the Rasperry Pi Zero port.
Created directory configs/pizero. Nothing there now but a README.txt file.
Add initial boot.c and memorymap.c files
Author: Alan Carvalho de Assis <acassis@gmail.com>
Add AUX/UART/SPI registers definition
Author: Alan Carvalho de Assis <acassis@gmail.com>
Pizero GPIO registers
* Initial commit to add GPIO definitions
* Add remaining GPIO registers definition
Alan Carvalho de Assis <acassis@gmail.com>
BCM2708 memory map: Add VBASE defintions; fix VCSDRAM address per Alan; move all virtual address to the bottom of the file to avoid confusion -- top is all physical address; bottom is all veritural address.
Add initial memory map to BCM2708/BCM2835

|

|

* Complete boot operations started in arm_head.S
|

*
|
||||
* Boot Sequence
|
||||
*
|
||||
* This logic may be executing in SDRAM or in external memory: CS0, DDR,
|
||||
* CS1, CS2, or CS3. It may be executing in CS0 or SDRAM through the
|
||||
* action of the BCM2708 "first level bootloader;" it might be executing in
|
||||
* CS1-3 through the action of some second level bootloader that provides
|
||||
* configuration for those memories.
|
||||
*
|
||||
* The system always boots from the ROM memory at address 0x0000:0000,
|
||||
* starting the internal first level bootloader. That bootloader can be
|
||||
* configured to work in different ways using the BMS pin and the contents
|
||||
* of the Boot Sequence Configuration Register (BSC_CR).
|
||||
*
|
||||
* If the BMS_BIT is read "1", then the first level bootloader will
|
||||
* support execution of code in the memory connected to CS0 on the EBI
|
||||
* interface (presumably NOR flash). The following sequence is performed
|
||||
* by the first level bootloader if BMS_BIT is "1":
|
||||
*
|
||||
* - The main clock is the on-chip 12 MHz RC oscillator,
|
||||
* - The Static Memory Controller is configured with timing allowing
|
||||
* code execution in CS0 external memory at 12 MHz
|
||||
* - AXI matrix is configured to remap EBI CS0 address at 0x0
|
||||
* - 0x0000:0000 is loaded in the Program Counter register
|
||||
*
|
||||
* The user software in the external memory must perform the next
|
||||
* operation in order to complete the clocks and SMC timings configuration
|
||||
* to run at a higher clock frequency:
|
||||
*
|
||||
* - Enable the 32768 Hz oscillator if best accuracy is needed
|
||||
* - Reprogram the SMC setup, cycle, hold, mode timing registers for EBI
|
||||
* CS0, to adapt them to the new clock.
|
||||
* - Program the PMC (Main Oscillator Enable or Bypass mode)
|
||||
* - Program and Start the PLL
|
||||
* - Switch the system clock to the new value
|
||||
*
|
||||
* If the BMS_BIT is read "0", then the first level bootloader will
|
||||
* perform:
|
||||
*
|
||||
* - Basic chip initialization: XTal or external clock frequency
|
||||
* detection:
|
||||
*
|
||||
* a. Stack Setup for ARM supervisor mode
|
||||
* b. Main Oscillator Detection: The bootloader attempts to use an
|
||||
* external crystal. If this is not successful, then the 12 MHz
|
||||
* Fast RC internal oscillator is used as the main osciallator.
|
||||
* c. Main Clock Selection: The Master Clock source is switched from
|
||||
* to the main oscillator without prescaler. PCK and MCK are now
|
||||
* the Main Clock.
|
||||
* d. PLLA Initialization: PLLA is configured to get a PCK at 96 MHz
|
||||
* and an MCK at 48 MHz. If an external clock or crystal frequency
|
||||
* running at 12 MHz is found, then the PLLA is configured to allow
|
||||
* USB communication.
|
||||
*
|
||||
* - Attempt to retrieve a valid code from external non-volatile
|
||||
* memories (NVM): SPI0 CS0 Flash Boot, SD Card Boot, NAND Flash Boot,
|
||||
* SPI0 CS1 Flash Boot, or TWI EEPROM Boot. Different heuristics are
|
||||
* used with each media type. If a valid image is found, it is copied
|
||||
* to internal SDRAM and started.

You might be able to use the hub to power the Pi Zero, but I was not
|
||||
able to do that; my hub would not switch on power until it was enumerated
|
||||
by the host (the Raspberry Pi Zero), but then I could not power the Pi
|
||||
with the hub because it was not providing power. Chicken'n'Egg.

* Perform application specific initialization. This function is never

* called directly from application code, but only indirectly via the
|
||||
* (non-standard) boardctl() interface using the command BOARDIOC_INIT.
|
||||
*
|
||||
* Input Parameters:
|
||||
* arg - The boardctl() argument is passed to the board_app_initialize()
|
||||
* implementation without modification. The argument has no
|
||||
* meaning to NuttX; the meaning of the argument is a contract
|
||||
* between the board-specific initalization logic and the
|
||||
* matching application logic. The value cold be such things as a
|
||||
* mode enumeration value, a set of DIP switch switch settings, a
|
||||
* pointer to configuration data read from a file or serial FLASH,
|
||||
* or whatever you would like to do with it. Every implementation
|
||||
* should accept zero/NULL as a default configuration.
|
||||
*
|
||||
* Returned Value:
|
||||
* Zero (OK) is returned on success; a negated errno value is returned on
|
||||
* any failure to indicate the nature of the failure.
