/* * Boot ROM Entry Points and such *//* These Blackfins all have a Boot ROM that is not reusable (at all): *  BF531 / BF532 / BF533 *  BF538 / BF539 *  BF561 * So there is nothing for us to export ;( * * These Blackfins started to roll with the idea that the Boot ROM can * provide useful functions, but still only a few (and not really useful): *  BF534 / BF536 / BF537 * * Looking forward, Boot ROM's on newer Blackfins have quite a few * nice entry points that are usable at runtime and beyond.  We'll * only define known legacy parts (listed above) and otherwise just * assume it's a newer part. * * These entry points are accomplished by placing a small jump table at * the start of the Boot ROM.  This way the addresses are fixed forever. */#ifndef __BFIN_PERIPHERAL_BOOTROM__#define __BFIN_PERIPHERAL_BOOTROM__/* All Blackfin's have the Boot ROM entry point at the same address */#define _BOOTROM_RESET 0xEF000000#if defined(__ADSPBF531__) || defined(__ADSPBF532__) || defined(__ADSPBF533__) || \    defined(__ADSPBF538__) || defined(__ADSPBF539__) || \    defined(__ADSPBF561__)	/* Nothing to export */#elif defined(__ADSPBF534__) || defined(__ADSPBF536__) || defined(__ADSPBF537__)	/* The BF537 family */#define _BOOTROM_FINAL_INIT            0xEF000002/*       reserved                      0xEF000004 */#define _BOOTROM_DO_MEMORY_DMA         0xEF000006#define _BOOTROM_BOOT_DXE_FLASH        0xEF000008#define _BOOTROM_BOOT_DXE_SPI          0xEF00000A#define _BOOTROM_BOOT_DXE_TWI          0xEF00000C/*       reserved                      0xEF00000E */#define _BOOTROM_GET_DXE_ADDRESS_FLASH 0xEF000010#define _BOOTROM_GET_DXE_ADDRESS_SPI   0xEF000012#define _BOOTROM_GET_DXE_ADDRESS_TWI   0xEF000014/*       reserved                      0xEF000016 *//*       reserved                      0xEF000018 */	/* Glue to newer Boot ROMs */#define _BOOTROM_MDMA                  _BOOTROM_DO_MEMORY_DMA#define _BOOTROM_MEMBOOT               _BOOTROM_BOOT_DXE_FLASH#define _BOOTROM_SPIBOOT               _BOOTROM_BOOT_DXE_FLASH#define _BOOTROM_TWIBOOT               _BOOTROM_BOOT_DXE_TWI#else	/* All the newer Boot ROMs */#define _BOOTROM_FINAL_INIT            0xEF000002#define _BOOTROM_PDMA                  0xEF000004#define _BOOTROM_MDMA                  0xEF000006#define _BOOTROM_MEMBOOT               0xEF000008#define _BOOTROM_SPIBOOT               0xEF00000A#define _BOOTROM_TWIBOOT               0xEF00000C/*       reserved                      0xEF00000E *//*       reserved                      0xEF000010 *//*       reserved                      0xEF000012 *//*       reserved                      0xEF000014 *//*       reserved                      0xEF000016 */#define _BOOTROM_OTP_COMMAND           0xEF000018#define _BOOTROM_OTP_READ              0xEF00001A#define _BOOTROM_OTP_WRITE             0xEF00001C#define _BOOTROM_ECC_TABLE             0xEF00001E#define _BOOTROM_BOOTKERNEL            0xEF000020#define _BOOTROM_GETPORT               0xEF000022#define _BOOTROM_NMI                   0xEF000024#define _BOOTROM_HWERROR               0xEF000026#define _BOOTROM_EXCEPTION             0xEF000028#define _BOOTROM_CRC32                 0xEF000030#define _BOOTROM_CRC32POLY             0xEF000032#define _BOOTROM_CRC32CALLBACK         0xEF000034#define _BOOTROM_CRC32INITCODE         0xEF000036#define _BOOTROM_SYSCONTROL            0xEF000038#define _BOOTROM_REV                   0xEF000040#define _BOOTROM_SESR                  0xEF001000#define BOOTROM_FOLLOWS_C_ABI 1#define BOOTROM_CAPS_ADI_BOOT_STRUCTS 1#endif#ifndef BOOTROM_FOLLOWS_C_ABI#define BOOTROM_FOLLOWS_C_ABI 0#endif#ifndef BOOTROM_CAPS_ADI_BOOT_STRUCTS#define BOOTROM_CAPS_ADI_BOOT_STRUCTS 0#endif/* Possible syscontrol action flags */#define SYSCTRL_READ        0x00000000    /* read registers */#define SYSCTRL_WRITE       0x00000001    /* write registers */#define SYSCTRL_SYSRESET    0x00000002    /* perform system reset */#define SYSCTRL_CORERESET   0x00000004    /* perform core reset */#define SYSCTRL_SOFTRESET   0x00000006    /* perform core and system reset */#define SYSCTRL_VRCTL       0x00000010    /* read/write VR_CTL register */#define SYSCTRL_EXTVOLTAGE  0x00000020    /* VDDINT supplied externally */#define SYSCTRL_INTVOLTAGE  0x00000000    /* VDDINT generated by on-chip regulator */#define SYSCTRL_OTPVOLTAGE  0x00000040    /* For Factory Purposes Only */#define SYSCTRL_PLLCTL      0x00000100    /* read/write PLL_CTL register */#define SYSCTRL_PLLDIV      0x00000200    /* read/write PLL_DIV register */#define SYSCTRL_LOCKCNT     0x00000400    /* read/write PLL_LOCKCNT register */#define SYSCTRL_PLLSTAT     0x00000800    /* read/write PLL_STAT register */#ifndef __ASSEMBLY__#if BOOTROM_FOLLOWS_C_ABI# define BOOTROM_CALLED_FUNC_ATTR#else# define BOOTROM_CALLED_FUNC_ATTR __attribute__((saveall))#endif/* Structures for the syscontrol() function */typedef struct ADI_SYSCTRL_VALUES {	uint16_t uwVrCtl;	uint16_t uwPllCtl;	uint16_t uwPllDiv;	uint16_t uwPllLockCnt;	uint16_t uwPllStat;} ADI_SYSCTRL_VALUES;#ifndef _BOOTROM_SYSCONTROL#define _BOOTROM_SYSCONTROL 0#endifstatic uint32_t (* const bfrom_SysControl)(uint32_t action_flags, ADI_SYSCTRL_VALUES *power_settings, void *reserved) = (void *)_BOOTROM_SYSCONTROL;/* We need a dedicated function since we need to screw with the stack pointer * when resetting.
