[PATCH v2 0/3] J7200/J721E: Fix USB DFU Boot mode

[Aswath Govindraju]

The following series of patches fix USB DFU Boot mode in J7200 and J721E
SoC's.

changes since v1:
- synced up the size allocated for tispl.bin and u-boot.img in dfu ram env
  variable with that of OSPI and eMMC dfu env variables

[PATCH v2 1/3] arm: dts: k3-j721e-r5-*.dts: Fix clock-names property in the usb0 instance

[Aswath Govindraju]

In the cdns3 usb driver, the clock name looked for is ref. Therefore, fix
the clock-names property in usb0 instance for proper initialization of
cdns3 usb gadget driver.

[PATCH v2 2/3] environment: ti: k3_dfu: Increase the size allocated for bootloader images in dfu_alt_info_ram

[Aswath Govindraju]

The size of u-boot.img is above 1MB and that of tispl.bin is close to 1MB,
in case of j721e. Therefore, increase the sizes allocated for tispl.bin and
u-boot.img to 2 MB and 4 MB respectively, in dfu_alt_info_ram environment
variable.

[PATCH v2 3/3] configs: j72*_evm: Define the buffer sizes for dfu

[Aswath Govindraju]

On J721e R5 SPL, dfu buffer for loading sysfw.itb image gets allocated
before DRAM gets initialized. So, the buffer gets allocated in MCU L3
RAM. The current buffer size to be allocated is 256KB  and the available
total heap memory is 0x70000 (448KB). This leads to NOMEM errors during
allocation.

In other cases when constraints such as above are not present fix the size
of buffers to the sector size in OSPI for proper functioning.

Also, if CONFIG_SYS_DFU_DATA_BUF_SIZE is defined and
CONFIG_SYS_DFU_MAX_FILE_SIZE is not defined then the max file size for dfu
transfer is defined as CONFIG_SYS_DFU_DATA_BUF_SIZE.

Fix these by setting appropriate buffer sizes in their respective defconfig
files and defining the max file size as 8 MB which is the default dfu
buffer size.
