Principal English Translation:
to come hither, to approach (see Karttunen)
Frances Karttunen:
HUĀLLĀ to come hither, to approach / venir hacia acá (M) This is a compound of HUĀL- and the verb YĀ, but the HUĀL- has been absorbed into the stem so that no other prefixes can intervene, and there is assimilation of the Y to preceding L. The YĀ element behaves like free YĀ-, being suppletive with HU(I). The present singular form is HUĀLLAUH, and the present plural is HUĀLHUIH. See HUĀL- the verb YĀ.

As Frances Krug points out, hualla was an unusual verb in discussions of the assumption or taking of a political office in the early seventeenth century, but it is found in a set of annals in association with an event in 1601. (Anales de Puebla y Tlaxcala, no. 2, 1524–1674, p. 810, p. 811)
