+/*! This function boot-loads the instruction and data memory (IRAM and

+    same image file used to burn the FLASH). During boot-load of each
+    Aquantia PHY, the processor is halted, and after programming is
+    complete the processor is released. Note that calling this
+    function leaves the daisy-chain disabled to prevent RAM over-
+    write. To exit MDIO boot-load mode, use the function
+    AQ_API_EnableDaisyChain.
+    Unlike most of the other functions in this API, this function can
+    operate on a group of PHYs simultaneously. This is referred to as
+    gang-loading. To facilitate this, this function takes as
+    parameters 3 parallel arrays: PHY_IDs, provisioningAddresses, and
+    resultCodes. The length of these arrays must be identical, and is
+    specified by the num_PHY_IDs parameter.
+    In order to check the integrity of the boot-load operation, a
+    CRC-16 value is calculated over the IRAM and DRAM. After the image
+    has been loaded, this value is directly compared against each
+    PHY's Mailbox CRC-16 in 1E.0201.
+    The value of register 1E.C441 must be the same for all the boot-
+    loaded PHYs. This will be checked before the boot-load is
+    performed, and if a non-uniform value is read from any of the
+    PHYs, the function will fail before any writes are performed.
+    A separate result code is returned for each of the boot-loaded
+    PHYs, in the OUT parameter, resultCodes.
+    Individual Port Return codes:
+    AQ_RET_BOOTLOAD_PROVADDR_OOR: The specified provisioning address
+    was outside of the permitted range.
+    AQ_RET_BOOTLOAD_NONUNIFORM_REGVALS: The values of the register(s)
+    that must be uniform across the ports being bootloaded were not
+    uniform.
+    AQ_RET_BOOTLOAD_CRC_MISMATCH: The image was completely loaded into
+    memory, but the after the port exited bootload the running
+    checksum that was read from the uP memory mailbox was not the
+    expected value. This indicates that the memory has potentially
+    been corrupted, and the PHY should be reset before trying the
+    bootload again.
+    Overall Return codes (the return value from the function call):
+    AQ_RET_OK: all ports were successfully bootloaded.
+    AQ_RET_ERROR: One or more ports were not successfully bootloaded.

+The MDIO access functions are required by the API to access the register space
+of each Aquantia PHY deployed in a system. The body of these functions needs to 
+be written by the system designer, as the method of accessing the PHY will 
+be unique to the target system. They are designed to be generic read and 
+write access functions, as the MDIO addressing scheme relies on each 
+MMD to maintain a 16 bit address pointer that determines the register where 
+the next read or write is coming from. Consequently, various levels of 
+optimization of the MDIO interface are possible: from re-writing the MMD 
+address pointer on every transaction, to storing shadow copies of the MMD 
+address pointers and only updating the MMD address pointer as necessary. 
+Thus these functions leave the MDIO optimization to the system engineer.
