[U-Boot] need clarification regarding mmc csd structure declaration

Hi,

I need few clarification regarding mmc csd structure declaration. I was taking Atmel mci as reference.

In ProductManualSDCardv2.2.pdf @ page 34 & ProdManualSDCardv1.9[1].pdf @ page 39, says

... ... ... C_SIZE_MULT 3 bit width ERASE_BLK_EN 1 bit width SECTOR_SIZE 7 bit width WP_GRP_SIZE 7 bit width WP_GRP_ENABLE 1 bit width ... ... ..

But in mmc.h file inside u-boot-1.3.4\include\asm-avr32\arch-at32ap700x.

Here, inside structure mmc_csd @ line

... ... ... c_size_mult:3 sector_size:5 erase_grp_size:5 wp_grp_size:5 wp_grp_enable:1 ... ... ...

So my doubt is, Shouldn't erase_grp_size come before sector size.

please correct me if i am wrong.

TIA
