 * see figure 6-22 in i.MX 7Dual/Solo Reference manuals:
 *  - IMX7D/S OCRAM free area RAM (OCRAM) is from 0x00910000 to
 *    0x00946C00.
 *  - Set the stack at the end of the free area section, at 0x00946BB8.
 *  - The BOOT ROM loads what they consider the firmware image
 *    which consists of a 4K header in front of us that contains the IVT, DCD
 *    and some padding. However, the manual also states that the ROM uses the
 *    OCRAM_EPCD and OCRAM_PXP areas for itself. While the SPL is free to use
 *    this range for stack and malloc, the SPL itself must fit below 0x920000,
 *    or the image will be truncated in at least some boot modes like USB SDP.
 *    Thus our max size is really 0x00920000 - 0x00912000. If necessary,
 *    CONFIG_SPL_TEXT_BASE could be moved to 0x00911000 to gain 4KB of space
 *    for the SPL, but 56KB should be more than enough for the SPL.

 * Pad SPL to 68KB (4KB header + 56KB max size + 8KB extra padding)
 * The extra padding could be removed, but this value was used historically
 * based on an incorrect CONFIG_SPL_MAX_SIZE definition.
 * This allows to write the SPL/U-Boot combination generated with
 * u-boot-with-spl.imx directly to a boot media (given that boot media specific
 * offset is configured properly).
