I've been trying to reproduce here but not having any luck so far.

I'm using the 2.31 Davincii Serial Boot and flashing utilites [1],
Mono 2.10 and the parent of commit
f1d2b313c9eb6808d30c16a9eb5251240452a56c: '4fff329
nand_boot_fsl_nfc.c: make "nfc" a "static const" pointer'

I build u-boot with 'make mrproper; make da850evm_config; make -j9 all';
I create an ais_output.bin with 'mono
/media/unixdata/src/OMAP-L138_FlashAndBootUtils_2_31/OMAP-L138/GNU/AISUtils/HexAIS_OMAP-L138.exe'
I erase the SPI flash with 'mono
/media/unixdata/src/OMAP-L138_FlashAndBootUtils_2_31/OMAP-L138/GNU/sfh_OMAP-L138.exe
-erase -p /dev/ttyS0'
I write the SPI flash with 'mono
/media/unixdata/src/OMAP-L138_FlashAndBootUtils_2_31/OMAP-L138/GNU/sfh_OMAP-L138.exe
-flash_noubl ais_output.bin'

and the contents of my OMAP-L138.ini are as yours:
[General]
busWidth=8
BootMode=SPIMASTER
crcCheckType=NO_CRC
[PLLANDCLOCKCONFIG]
PLL0CFG0 = 0x00180001
PLL0CFG1 = 0x00000205
PERIPHCLKCFG = 0x0000000a
[EMIF3DDR]
PLL1CFG0 = 0x15010001
PLL1CFG1 = 0x00000002
DDRPHYC1R = 0x000000C4
SDCR = 0x0A034622
SDTIMR = 0x184929C8
SDTIMR2 = 0xB80FC700
SDRCR = 0x00000406
CLK2XSRC = 0x00000000
[INPUTFILE]
FILENAME=u-boot.bin
LOADADDRESS=0xC1080000
ENTRYPOINTADDRESS=0xC1080000

I would like to help you debug the operation of UBL-free boot with
relocation -- can you give me more details on your setup to help me
reproduce here?

Best Regards,
Ben Gardiner
